Looking at some of the old records of Missouri gunsmiths in "Missouri Gunsmiths to 1900" book - census records, estates, etc. it appears that many made use of various parts made by someone else. Sand-casting a trigger guard, for example, could be done by one or two people. Freshing out or rifling a barrel - one man job. Forging a damascus-type barrel using strips of iron around a rod or creating a lock from scratch? - that'd be really hard.
Looking at originals from the 19th century, made before electric motors, etc., has always fascinated me. Not hard to understand why firearms were treasured, handed down for generations.
