Okay, starting from scratch - -
go to
www.google.com
In the "search" field, enter, "Investment casting firearms."
This will tell the story of lost wax casting and firearms investment asting than I could in a few words.
Traditional manufacturing methods had to do with forged steel. You took a hunk of top grade steel and forged it into rough shape, then machined, ground, and milled away everything that didn't look like a gun. Much handwork, very tedious, and, as hourly wages increased, these methods got to be extremely expensive.
lockwork is what makes the action of the firearm work. Part of the old, "Lock, stock, and barrel" expression.
transfer bar ignition? It is a safety system - - Prevents the firing pin from making contact with the cartridge primer until the trigger is all the way to the rear. Try Google again.
coil mainspring? Older model revolvers, and many autoloaders, usually had a leaf mainspring to provide energy to the hammer.
Go to the blue bars at the top of this page and find the "Search" function. Enter "Python" and see what an old style Colt's double action sixgun looked like. Beautiful - - and expensive.
Good luck to you - -
