With an assistant, I completed a search of bore measurements and wall thickness measurements of a pair of William Evans sidelock guns at an Alderfer's auction several years ago, using a Galazan bore micrometer and a Manson wall thickness gauge, in about twenty minutes. That included the transcribing of the measurements onto a legal pad. This allowed me to purchase a cased pair of second tier London sidelock guns in high condition for a price that anyone without these measurements wouldn't have had the nerve to purchase at any reasonable price. The guns were perfect, original, no work done on the guns including extending chambers, all bores completely untouched. My tools cost me about $225.00 and I have used them for decades.
