Dave, I can understand the T wrenches being needed as a special tool to lock the adjustments in place but they could have just used a yard stick and ruler to get the drops and a protractor for the pitch. I have the R. Louis Co. Shotgun Combo Gauge which does the same thing as your main beam does but is held in place by magnets.

Dave's is still better adapted to the Parker Bros. try gun.

Chuck, These tools are replicas of tools made by Parker Bros. Not something I dreamed up. And trust me when I tell you the craftsmanship in these tools is just as good as a Parker shotgun. These men were real craftsman.

Dave, let me know if additional sets are available.

There were approximately 15 or so ever made, in and around 1915. Apparently these Try Guns were sent to various & select distributors around the country. There is an article on Try Guns in the Double Gun Journal, ( Vol 8- Issue 2 ) that goes into detail about Parker Try Guns.

Try gun details

What was the purpose for the 3 holes in the rib? Attaching a beam to set drop? Or just later day desecration? Thanks

Bill,That is where the main beam mounts to the gun.

The above photos I posted are of a try gun with the tools that Dave is making duplicates of for another try gun that has no tools. How the tools get separated is one of those mysteries, but it happens. So in the interest of Parker knowledge, who knows how the ring sight at the muzzle end is used? We'll provide the answer tomorrow if somebody doesn't come up with it first.

The try gun tools are serial numbered to the gun.

Bruce, I have no idea how the ring sight is used, all I know is that I want one. Dave, what about my request for a duplicate set of tools for my try gun?
