Lee,
If you get inspired to do another one I'd love to see a NM Blackhawk in .327 Federal Magnum. Bowen and other gunsmiths offer conversions for .32 Single Sixes but I've never seen a Blackhawk in .327 Fed Mag. With the heaver frame I'll bet it would be a sweet shooter and the extra cylinder mass would help with the high pressure of the .327 round.
I'd also like to see that lettering machine that you described earlier in action.
I love threads like this one where people demonstrate their skills and take us along for the ride!
