Hi Gary,

The catalog that I have, which is undated, only lists a safety
for the Mauser, the lever on the safety I bought is identical to yours. My safety is unmarked, so I can't conclude that it is a Jaeger, but given the resemblance and the wide variation between
Jaeger sidemounts, it would not surprise me that it was. Perhaps, someone out there has other Jaeger catalogs and can contribute.

Fred
