I got another dynohub, a nice 32H front one, which I overhauled successfully and am now idly trying to figure out exactly how old it is.
I know, there's a date code. And I found it, too. It reads:
4 5 6
which I figure I can interpret either as 4/56 or 45/6 or as just some random numbers.
But I also know these hubs changed little by little over time. This one has an oil port, a feature I've never seen on a front dynohub before. The dynamo-side face, where the electrical terminals are, is a dull matte colored stainless steel, just like on a DynoFour hub I have (which is dated 50 2).
So, my question for those of you who have dynohubs dating to the period 1945 - 1956: does mine sound like a '45, or a '56?
