Last year I bought a very, very nice Husqvarna Mauser 98 with an FN postwar action (date code 1948) that came with a curious side mount base for a scope. A few months back I did a posting about my quest for a suitable upper mount.

After finding photos of some of the hideously expensive, and to my eye, ugly, original detachable scope mounts, I gave up the quest and mounted an old Weaver 2.5x offset (à la M1 Garand C/D) using a unitized pair of air rifle rings made for an 11mm dovetail.

This worked OK to a point, but it ruined the balance of the rifle and looked like crap. I kept thinking about this and last week I finally decided the old side mount had to go.

It would appear that the mount is secured by just three screws. None of them would budge, despite grinding a tip to fit the slot and using a Chapman ratchet handle with a cheater. I assumed permanent Loctite to be the culprit, so I took a medium wattage electric soldering iron and held it on the head of a screw for about a minute. After two applications of heat I managed to break tension on one screw at a time without overly buggering the slots. Once the three screws were removed, I took a small hammer and tapped the base, expecting it to fall off. Instead, it rang like a bell. On closer examination I could just make out some shiny spots within one of the screw recesses -- the mount had been sweated to the receiver! I guess that explained why the screws weren't staked.

I used a propane torch to slowly heat the mount (no heat was applied directly to the receiver!) until I was able to tap the mount free. I then heated the siderail just enough to wipe off the remaining chunks of soldier still adhering.

While the rifle as a whole has a remarkable degree of (I believe) original finish, I found lines of pitting hidden under the mount next to the soldiered area, on both receiver and mount.

I've done some initial polishing and applied cold blue, but I still have more polishing to do on the receiver.

I cut the heads off the mount screws to make temporary plug screws while I wait for some proper screws I ordered to arrive from Brownells. I also ordered a Warne 3-screw steel bridge mount and a Timney Buehler safety, so that when complete I can finally position a scope on this rifle the way nature intended.

I also still need to patch the small cavity in the stock that made room for the side mount base. An easy task once I find a sliver of matching wood.

Some progress and a couple of new photos.

This week I polished the side of receiver to a degree I can live with, AcraGlas-ed a sliver of walnut into the stock fill the inletted cavity for the old side mount, and installed a Timney Buehler-type safety. Now I just need to have the receiver d&t for the Warne base I ordered and I'll be ready to add the vintage Weaver 2.5x scope I've set aside for this rifle.

The old mount used three screws with a thread very similar to 8-32, but not quite the same -- possibly a M4-.7 metric thread. The old mount base looked like other commercial Swedish mounts, so perhaps. They were definitely not 8-40 as I expected -- I ended up retapping and using cut down set screws rather than gunsmithing fill screws. I gave each of them a healthy dollop of green Loctite 620 to keep them from moving around.

This story still has yet to reach its conclusion. I left the rifle with an unnamed local gunsmith at the end of July 2019 to have the Warne/Weaver base installed. I finally retrieved the rifle last week -- the base still unmounted! This smith had been closed for the last five months to catch up on old jobs so he could sell his business and he still had not gotten around to my rifle.

I dropped off the rifle at Sportsman's Warehouse on Tuesday evening to send to their gunsmithing service in Utah, in hopes of getting the new scope base mounted and then finally posting a completed photo.

BTW, the line for customer service at the local SW's gun counter had four people ahead of me -- it was a 75 minute wait! Had a nice chat about pump shotguns with the fellow in front of me.
 
Sounds like a common thread....I think alot of gun nuts get into smithing cause it will be "fun" then at some point realize they don't wanna, or can't do it anymore, course by then there is a back log of stuff.
My local Smith's the opposite....I'm pretty sure he's into guns cause he likes working on them.

Here's hoping the SW guys get your bases installed and your gun ready to go in short order.
 

Thanks! I bought one of those, then had second thoughts and went with Warne's two-piece mount instead. As you can just make out in the prior photos, the receiver has the raised, military-type rear bridge for stripper clips, and I didn't want that milled down for a standard rear commercial Mauser base.

Makes sense, I wouldn’t want to take off any metal if I didn’t have to. So is it a commercial 98 action or a military? At a second glance it looks military but I’m not real familiar with FN actions other than the Sears JC Higgins Model 50.

It's a bit of both -- it has the military hump on the receiver bridge and standard flag safety, but the left receiver rail is solid, without the military thumb notch. My other Husqvarna in .270 (top) also has an FN Mauser 98 receiver (dated 1950), but by that year they had dispensed with the receiver bridge hump and gone to a lower-profile side safety lever.

I suppose I'm partial to the way both my other commercial Mausers look with the 2-piece scope bases. The lower rifle with the full stock is a .30-06 Monkey Wards rifle made in the 1960s by Heym with an intermediate-length action.

My understanding is FN made commercial 98 actions and also made some rifles with military 98 actions they acquired. Is that true?

I'd did some re-reading to refresh my memory about the basic facts: during WWII occupation the Germans looted FN rifle production machine tools rather than using them in situ. They used whatever parts were on-hand and then concentrated on pistol production and repair: P35, M1922, some P38 components. Once liberated, FN got back on it's feet with a contract for refurbishing American smallarms.

In 1946 FN resumed Mauser production. During the postwar era the Mauser was primarily a commercial product, though they did receive contracts for overhauling and/or converting Mausers to new chamberings from smaller countries such Columbia, Haiti, Israel, etc. Some of these refurb contracts would have included non-FN Mausers -- many if not most Israeli Mausers were Czech manufactured, for example.

New FN military production focused on the Browning Hi-Power and semi-auto rifles like the FN49 and FAL. For the full FN Mauser story (with photos!), this is the book:

I don't believe Husqvarna ever produced a true Mauser 98 action of their own. They made the Swedish M96 military rifles and sporters, but for their 98 rifles they used FN 98 actions plus their own stocks and barrels. This changed with the introduction of the HVA action in the early 1950s, a fine action which was basically a modified 98 with some production simplifications.

I wish there was a good book on Husqvarna arms in English -- does anyone know of one?
