+++++++++++++++++++++++++++++ Must be something in the water this Spring; I'm about to try putting a set of these on my Rauler.

But, a note of caution: there are several nearly-equal 3-bolt circle diameters. I have a lovely Chater-Lea inch-pitch 22 that's off by about 1 - 2 mm, and takes ~7mm bolts; would need modification to mount on a Campag-continental standard arm. the ChaterLea might have enough "meat," but would need proper jigging to re-bore off center, or careful filing.
