Kurt_701,

That patent is for an earlier mount I believe, not the one that Long Range has questions on.  The turret design and mount is different.  I searched and could not find the patent on the later version.  Lyman has several later patents by designer Frederick Kuhn listed for "Telescope Sight Mounting" without photos.

Lyman’s standard rear mount for the 438 scope is a non-click design, but Lyman did offer an upgraded rear mount for the 438 with clicks which is similar and may be identical to the STS mount.  Click on the following link: (You need to Login or Register to view media files and links)
The 438 upgraded mount and the STS mount are both 3-point rear mounts, meaning the scope body is held in place by 3-points (two turrets and a spring loaded plunger).  The patent that Kurt referred to is for a 4-point rear mount with two turrets and two opposing spring loaded plungers.  You'll note that the turret design in the patent is similar but not identical to the exploded drawing that RSW provided.

Mac,
These are pictures of my 438 turret. It's the optional, 4 point and has 1/2" clicks. Note that your brochure says NEW 3 point mount with 1/4" clicks.

I believe the 438 and A5's, came out around 1937. Red, Bill and BP could be more accurate, I'm sure.

Also included is a picture of the Lyman A5 turret. It's not mine. They appear to be the same.

Thank you, very much for that 438 brochure. I didn't have it.

I received a 15x STS scope today that i bought on eBay.  It has another variation that I haven't seen.  Instead of the pads on the ends of the adjusters, there is an 'L' shaped piece of material. (see arrows).

They are quite common Jack and the ones I prefer to have. They also made some with Nylon pads or a similar material but they also wore a tube diameter groove in them rapidly and thus making accurate adjustment's a real challenging task. I have also seen the circular pads made out of some sort of steel and had to replace one due to wear as well but also not as severe. They were also free to rotate on a pin and I believe the Nylon pads did not the best that I can now recall.

Jack it sounds very similar to the same circural swivel steel pad I replaced for a friend. I believe you said you had a mini lathe and if so very easy to make and I don't think the ability to have it swivel is of any advantage. I will try to find a picture of the one I made it simply slid into the hole you mentioned. I lost allot of my pictures but I will try to find it for you if I still can. Are both adjustment pads missing or just the one if not they are identically the same and are easy enough to copy. I also did not have to remove the mount just simply backed all the way off the adjustment and it slid right in the stem that went into the hole was not long enough to require doing so and it was the elevation pad.

I just bought a Lyman Jr with the 3 point adjustment similar to BPJack's photo.  There are no clicks.  In a little plastic bag came two "U" shaped pieces of homemade, non-blued steel.  The bag was marked "CLICKS".  From the photo, I now know how they are situated.
