Well I have it in hand so to speak, it looks rather genuine from my inexpert point of view, but genuine what is the question. Turrets are locked solid, through age or design isn’t certain. However my guess is that someone went to the trouble of stamping model onto this for a reason. I am expecting there to be rather few internals. That said it will look good on display.
All that said I will be looking to run it past an expert, or as close to as I can find.
