Gun No.1 is a Model 58 .41 Magnum Military & Police manufactured in 1967 to 1968.
Originally introduced in 1964 and discontinued in 1977 with around 20,287 units manufactured, it was not the success S&W expected in the police market.
The Model 58 had a service trigger and hammer, fixed sights and Magna combat grips. Yours should have the uncheckered diamond around the grip screws if they are original to the gun.
In 2006 the Standard Catalog of S&W gave the following values:
ANIB $800, Excellent $700, Very Good $450, Good $325, Fair $265, Poor $175.
Gun number 2 was manufactured in 1966-1967.
Gun Number 3, the .41 Magnum Target was manufactured in 1979-1980. The Model 57 was produced from 1964 to 1993, with a number of 4 inch tapered barrel mountain guns produced in 2005. The Model 57 came with target trigger and hammer, adjustable white outline rear sight, and Goncalo Alves target stocks.
Gun number 4, the .22/32 Kit Gun Stainless was manufactured in 1978 or 1979. Originally produced as the blued steel Model 34 on the .32 caliber 'I' Frame, hence the .22/32 name, the Model 63 was only manufactured on the slightly larger J frame.
Gun number 5 was also produced in 1978 or 1979. 1979 seems likely as the serial range for those years was M100000 to M130000.
Gun Number 6, the Model 36 Chiefs Special was produced between 1957 (serial number 125000) and 1962 (serial number 295000). Yours should have a flat latch and this may bring a small premium if sold to a collector.
Gun number 7, the .357 Combat Magnum Stainless was produced in 1975. First production models had a stainless steel rear sight, later guns had a black rear sight with white outline.
