Sounds like you're gonna have a cool bike. Pre-war? Pre WWII? That'll be great.
The board track racers certainly look great. I don't think I'd like those drop-down handlebars, though.
That's about the only suggestion that I can think of right now. But when you have questions, you'll be amazed at the good advice you can get here. But before that you should read as many of these threads as you can. You'll learn a lot that way.
Have fun.
