A) Gorgeous work, as always.
B) Does the groove that tuns along the side of the slide serve a functional purpose, or is it purely for esthetics?
C) I would assume the slide is a certain thickness and weight for a reason. If you machine that much metal out of the slide does it weaken the slide? Does the weight loss of the slide require different weight springs to keep the timing right when cycling?
Again, that is one drop dead gorgeous piece of work.
