You just couldn't resist coming out, could you Danny?
Glad you took the plunge and the pistol is not tucked away in some nameless collection, where it would never see the light of day.
If Walther's records are incomplete on this matter, I'm not sure what could prove the pistol is genuine beyond reasonable doubt. If a forensic examination (who would carry out such a task?) revealed the finish was touched up at some stage, would that cast doubt on the results?
This pistol has certainly provoked an interesting debate across the world, so hope you enjoy it.
Kind regards,
John
