Looking through some old (really, really old) gun rags kept around for 68 years, moved many times, and came across this 1953-1954 Gun Guide. Since I was only 9 I don't think I bought it...but here it is.
Thumbing through to look up prices in those days and options (stocks, sights, barrel lengths, etc.) I came across this fabulous article on the manufacturing process from raw steel to out-the-door by Smith & Wesson...complete with sixty (60) individual photographs, depicting every step of the way!
I didn't see any photos of Dr. Roy, but he might remember some of those pictured (and named) like the father son team that are pictured looking over a machine grinding extractor rods...Howard Blaisdell, age 75 with 52 years of service and his son Howard Blaisdell Jr, age 41 with 16 years of service at the time the pic was taken for this publication.
Since most of the machinists pictured wore typical shop clothes, most of the folks pictured with suits, ties, vests were probably engineers, but every photo showed individual, personal involvement at whatever operation, and even with that, no less than six quality control checkpoints and hand work.
All in all..........no wonder we love these old wheel guns. Made with superior craftsmanship in days when quality counted and you got what you paid for.
Enjoy
