Here's the other photo I mentioned. Not as clear a photo as the first one, but you can see the butt of the revolver. It looks like a pre-Victory, with the chequered stocks. My Victory model is pre-"V" prefix, but just enough later to have the plain stocks.
I've also just completed assembling a Canadian Pattern 37 web belt, holster and ammunition pouch to match the configuration he's wearing. Just need the Harley now. ;-)
He unfortunately passed on when I was quite young, so didn't get a chance to ask him about his experiences.
