Pete, the one Hamilton is doing is based on an OM 357 flat top. It has a 5 1/2" octagon barrel, Clements OM regular frame bisley hammer, a #5 base pin latch with a #5 base pin and a Ron Powers two piece steel grip frame modified for the one piece ivory grips that will be done by Paul Persinger. Turnbull is doing the color case work and it will get a black powder chamfer along with the usual action job, tightening, lineboring etc. The hold up has been on getting the #5 latch parts made. Hamilton hopes to have them in hand sometime this spring then it should get back in the works line. It would have been done months ago except I opted for the #5 latch which set things back aways.
