BYF 41 Serial Number 3061 M has two 135 proofs
(Correction: I was notified via email by Frank that there is no Luger # 3061 m BYF 41... I have rechecked my photo archive and Frank was correct. I misread the chamber date while reviewing the photos I had available. Thanks for catching that mistake Frank. -John S.)

Hope this helps in your search for the transition point.
My personal byf 41 is 2871 and has two 655 proofs but unfortunately, I don't remember the suffix letter and it is not here in the office... it is locked away in a safe...about 60 miles from here...

I would bet that Bill Munis could have more info about where the transition took place... How about it Bill? Can you hear me NOW? Good! [img]biggrin.gif[/img]
