Pretty broad question where do you want to start?
I recently posted the base chart in the vintage section. There are a few places making repro bases.
Unlike modern gas purged optics dont be afraid to tinker with these they do come apart and are easy to service. I have replaced crosshair wires before and repaired clickers, like I said very easy to work on.
Aside from that all I can say is congrats, engoy and post some pics. They are cool scopes for a number of reasons.
