Has anyone seen a NM with the later Stevens sight variation without the elevation binding screws/or plugged holes like this one? I'm guessing this pistol was made in mid 41 because that's when this sight starts to show up on the Service Aces.
I know that's the same sight used on 1st series Woodsman match targets. I thought the one with neither was the first variation, then added screws to prevent movement, then plugs. Any clarification will be appreciated.
First Type Stevens Rear sight had the two adjusting screws in the rear sight blade and were used on the earliest Colt MT Woodsmans; Shooters complained of the use of friction to hold and maintain elevation was causing problems and was unacceptable. The later Rear Sight was an improved version with a coil spring tension and other changes that did away with the two friction binding screws that adjusted elevation. Roper gives a detailed description of the rear sight evolution in his book "Experiments of a Handgunner" on pages 56-58. It was his improvement that resulted in the last version that was used on the later Service Ace and NM's. IMO, I think some early rear sights have been modified by using the Roper spring Improvements and replacing the two screws with dummys for appearance. Later versions did away with the binding screws. Fig 14 on page 57 shows a picture of a similar MT Woodsman modified rear sight with dummy screws in place. Jackson.
Appreciate the info, I think l will track down the Roper book as it sounds interesting. I also got the Colt letter for this NM today, it confirms that it shipped with a adjustable rear sight to Stubbs Hardware, Savannah Ga in May 1941. It was manufactured in April 1941
The earliest Colt NM adjustable sights had the windage screw hole situated to be mainly through the frame of the pistol. Later sights have that screw hole moved up to be mainly in the sight body as shown in the above post.
