Digging up a very old post I know, but I thought it would be better to keep relevant information in 1 spot rather than start a new thread.
I just acquired one of these "circle A" mausers. serial #1017, no import marks, no indication of RC. I saw it, didn't have a clue what it was and figured I better buy it.
Mine only has circle "A"s on the barrel and receiver. Barrel underside has a "K", the circle "A" and 38R60, top is marked 7.92
The full serial is located on the barrel, receiver, trigger housing, floorplate, butt plate, sight base, sight, and the bands.
Floorplate is standard in appearance
The last 2 numbers are located on the bolt release, sight slide, follower, and screws
Front and rear sight bases have a "K" where a waa would normally be.
trigger has a waa 655
Bolt doesn't match and is waa280.
Stock is walnut, handguard is marked 1011 inside, the 10 is well struck, the 11 is very lightly stuck.
