Jkob,
Thanks for the offer.
Upon further examination, it appears as though a piece of the bolt sleeve behind the notch that was filed to install the safety has broken off. (Maybe it was filed too deep 60 years ago?)
So I'm going to order a new bolt sleeve and install a safety.
Does anyone have suggestions for the best two position safety?
Buehler?
Old Redfield?
Mark II?
Other?
Also, will a bolt sleeve for a 1903 fit on a 1903-A3?
Thanks for advice!
Tom
