BYF 41 question

[Roh]

Greeting to all, from South Florida,



I have noticed, certain BYF 41s, the details of E/655 E/655 right receiver acceptance stamps are very light or faint, barely readable,

and on others they are very crisp.



I just purchased a BYF 41 " Black Widow" serial # 8906z, black grips, I cannot tell if its e/655/655 or e/655/135.

All the other proof markings are fine, I do not suspect that it has been re-blued.



Can anyone tell me according to the serial number, if it should be e/655/655 or e/655/135, also the approximate month/year of production.



Thanks to all,



Robert
