I'll take measurements tomorrow.
From what some have posted on later models, (not sure when they changed) buck horns wrist angle were changed.

 

Yeah, I thought about that and the wrist angle is crucial. Hopefully, I'll be able to find a set of originals but we can just about guarantee that they will need to be re-chromed. I would love to find a pair in 1-1/4" but I think that idea is probably a no-go.
