Winchester 1890 take-down screw

[ActionClaw]

I have a Winchester Model 1890 Pump Action Rifle chambered for the .22 WRF
Serial Number: 255xxx , from what I can tell, a Second Model, manufactured: 1905

On most (probably all) second & third models I've seen, the take-down screw is large slotted, grooved-edged "thumbscrew" that sets higher than the surrounding surface area. Mine is a recessed screw that otherwise fits and looks correct. I'm assuming that, sometime in the last hundred or so years, the original screw was lost and that this one is a replacement. Were any Winchester 1890s, at any time ever produced using a screw other than the usual type described?

No, not that I'm aware of.

All I have ever seen have the large coin slotted head, and are held in the lower receiver assembly screw bushing when loose for take-down by a tiny tapered pin on the other end.

You can get a newly manufactured replacement screw here.

You can make the tapered pin from a piece of wire.

Yea, that's pretty much what I suspected.
Thanks for the (super speedy!) response and links.
