Thanks John, I'm pleased that they appear to be genuine. Here's the photo that you requested. I'll give you the data on the pistol too - it's a BYF 41 S/N 8247 - all matching. I can't work out what letter the script suffix is and will post it for guidance once I manage to take a clear photo of it. On the minus side it's been refinished, probably in East Germany as there is an X in a circle marked on it - plus, of course, it's a dewat. ( No prison for me please.)
