Bob,
Not trying to be a wiseguy, but I honestly don’t know most of the measurements from the gun that I built.
I can tell you this. It’s a .45 cal, 44 inch, B weight barrel, either a Getz or Rice, I don’t recall which. Chambers gunmakers lock. LOP is approximately 13.5 to 13.75 inches. I used Jim Kibler’s butt plate casting, but I used another modified larger guard so that I could accommodate double set triggers which Eister did sometimes use.
The stock profile started out as my standard generic stock profile with a little cosmetic tweaking. (Probably could have used a little more tweaking to truly get a more Eister-like profile)
Everything else is eyeballed around those features.
Jeff
