As I said in the original posting, I am changing the rifle to 7x57 R from the 6.5x53 R. Wanting to do that of course could mean issues with the magazine system and feeding. Early on I made up some dummy 7mm cartridges and tested to see if they would fit and feed. Imagine my joy to find out it would work without major issues. So I didn't need to develop a new mag box. One of the things I did not like about the original Dutch Mannlicher was the trigger bow. To say the least it was BIG. And was not conducive to adding double set triggers. There was lots of room inside the bow but not in back for the set trigger. So I have attached a mock up picture of my modified mag box with double set triggers and a new trigger bow. The space between the front of the new T bow and the back of the mag box allows for access to the cartridge clip release button, so that works nicely IMO. The design process is one of the more enjoyable parts of any project!

It's a bit more than that. Just like a slide rule is a bit more than a generic yardstick. No, not really, a venier scale device is just a measurement method/device, but a slide ruler ain't no yardstick and you can't measure anything with it. A slide ruler would be more akin to a generic scientific calculator. In fact it was until HP started building calculators and ended the need for them. I haven't used one in more then 50 years, but I think I still have one in my office desk.

Okay. If ya got all the answers, I guess you are good to go. I've seen too many homemade and even some commercial sights that were nicely made except for being wrongly calibrated.

Apparently you missed this statement in my earlier posting, "It will be final finished and elevation and windage hash marks added after testing." Defined, "elevation and windage hash marks", ie: the venier scales. And "after testing", means shooting the rifle on the range at known distances so as to calibrate the markings to actual
I hope that answers your question

Origin of the DST's, Lynn?
When you disassemble the sight for finishing would it be possible to see how you designed the cam/spring arrangement for the pivoting post? Thanks.

The double set triggers are NOS sold by Brownells. They were typically used on Mausers. I have them so decided to use instead of making from scratch.
Yes to your second question

Gary, here is a picture of the set triggers all inlet into the rifle bottom metal and cross pinned. And a picture of the peep sight internal mechanism that allows the swing arm to move out of the way of the bolt handle and return to battery position. Its just a camming action, however the way I do it to cut the diameter of the cam surface a little bit smaller then the shaft diameter. This means you can spin the swing arm around 360 degrees and out of the way if desired without any other retaining feature to keep it held in place. I think Lyman used an additional pin or screw to accomplish the retaining of the swing arm. I can't actual swear to that as I have actually never seen or examined a Lyman 36 other then in pictures

The trigger guard is installed. There is a claw on the top front of the guard that I silver soldered on which fits into a mortise cut in the bottom metal in front of the triggers. Now need to get the sear to function and fire the striker when the trigger is pulled either by itself or in conjunction when the set trigger is cocked
