The Smith & Wesson Model 1 was issued in three different variations. Each issue included technical advances and redesigns. Listed below are the specifications of each issue  and what was changed as well as a visual example of each variation.

Model 1 - 2nd Issue
S&W Model 1 - 2nd Issue
The 2nd Issue of the Model 1 shares the same grip and frame design as the 1st issue so they are often confused. There are several notable differences listed below.

•             the hammer was now made in one piece

    2. If you can't find the actually replacement part, you could consider fabricating a trigger leaf spring.
      I have made cylinder hand springs and simple leaf trigger springs from pieces of spring steel I broke off of a coiled flat spring taken out of an old vintage wind up alarm clock.
      Someone out there might know the dimensions,specifically the thickness of the metal, and you can easily find an alarm clocks coiled flate spring on eBay for $5 or $10.
      Spring steel cannot be sawed thru, so to shape it, you use a file, and to cut off a piece of the right length, just hold it in a vice, you can bend it back and forth until it breaks off.
      I recently made a cylinder hand spring for a Norwich Pistol Company "Protector" 32rimfire spur trigger revolver without knowing any measurements in advance.
      I paid $7 on eBay for a coil flat spring which was taken out of an old alarm clock, and after a bit of trial and error, filing to remove and shape the steel, it works fine and that revolver is fully functional and safe to shoot.
      Good luck!

  4. S&W made some high quality and innovative cartridge firing handguns right from the the start!
    I am fortunate to own a tip-up No.1½ "New model" that is in such nice condition, that it is hard to believe it was made in 1874-75!
