I got mine about 20 years ago. It was rebarreled, refinished (all Nazi proofmarks were removed), an Israeli Defense Force crest on the receiver and looks like it spent all its time on the rack until I bought it. It was made by FN for the Germans in 1944.
As I understand it the Israelis were given a lot of captured German weapons (Mausers, P38s, MG42s, etc) and the 8mm Mauser was their first standard cartridge. I got some Israeli 8mm ammo some time ago. When they started getting FN/FALs ib the 50s they took all these Mausers and rebarreled them to 7.62 NATO same as the FALs. They continued to use them as a reserve weapon and to arm support personnel into the 70s. I think I remember seeing an IDF soldier in a photo with one during the Yom Kippur war.
