The conversion seems to be well executed.
Andy Horvath is still working and could still do the conversion.
My Model 28-2 became a 45 ACP revolver many decades ago. Nothing like building the revolver you want!

…If there's a recommendation out there for a currently-operating smith to do a conversion, I am open to suggestions
…
The one caution is that because the cylinder lock cuts on an S&W are over the chambers, look for ones that are too deep.
Maybe an unfluted, recessed .44 Special?...Paired with a tapered 3"barrel and a square butt?...Sign me up...I keep playing with the idea of making a cylinder mostly just to give it a shot. LOL
When Skeeter was writing about these conversions, this issue only affected the .45 Colt cylinder re-bores. One converted cylinder actually cut through the chamber.
