My reference point is journeymen 18th century tradesman... my former co-workers. ;~) None of their work was crude. I wasn?t even considering the rough work that may have been done by non-professionals at home...
I recall a visit from master engraver Lynton McKenzie. This guy was world renowned (now deceased) and I was dumb struck when he praised Wallace Gusler's engraving skill. This because Wallace used what Lynton described as a sharpened nail to do his work whereas he himself used the finest hand engraving tools and fixtures available. The notion that tools were a limitation to quality and fineness quickly faded away as I watched journeymen work and saw the fineness of their work. I learned a lot from them...
One of Wallace's guns... hand forged and filed barrel, lock, etc.
