Did the Remington Model 12 .22cal (serial number range of 704k) ever have a hole in the receiver just above and to the front of the take down screw? I have a model 12 and there is a hole drilled into the receiver. The hole is threaded and goes to the inside of the receiver exposing the internal "bolt". I can not find a single model 12 with the same hole mine has.
Thanks.
