Go read some Wonderful WWII reminiscences from Hubert Hubert's dad, with some fun facts about the Walther P38 for good measure.
"I helped them make the arm bands they wanted for their unit which was about 200 strong, stamping them and painting them with the tricolour & the Cross of Lorraine. Then they realised I was a trained armourer so they dug up all the old guns they had hidden in the church yard next to the farm house under the grave stones in the cemetery and I cleaned Lugers, German and Italian automatics and shotguns which would have blown up if they had ever been fired."
