I acquired this from a friends estate the other day, I bugged him for it for years before he passed away, I was surprised to hear from his family the other day with a call saying come and get it , it's yours, if you want it. It's a naval salute cannon, I started the restoration process on it yesterday, and spent all day working on it today, I need a firing pin for it, if anyone knows where I can get one or have a set of prints so one can be made I would appreciate any information. Here are some pictures before and some work in progress pictures as well.

The buttstock and sight blade make me think it had a more practical use- line throwing perhaps ?

Firing pin aside, what are you going to use for a cartridge?

Same gun, different mount?

It has probably 4" thick round piece of wood that it was mounted to, I will sand it and refinish it for a pedestal, I believe it should suffice for stability. Maybe my wife wont mind if I bolt it down in the living roomDI5

A 37mm cartridge sits flush in the breech, I have some spent CS cartridges that will work perfect and they are reloadable also.

Or umm flares for the replica 40mm launcher under the M16/AR15 platform?

That looks just like it, less the pedestal mount and stock, not sure if the barrel is bronze on this one though, I start that project this week, all the small parts have been polished with Brasso, mount is all ready to be put back together. And I am shocked what that one sold for, thanks for the link.

As a line thrower the bore would be bigger than 37mm. They used a line tied around a weight with a "monkey fist" knot. The layers of rope made it fit the bore.

Everything I need to know I lernt off the intarwebs.

And there is a company called Naval Company in PA, different town but they sell the H&R based line thrower today. You might email them for history?

Apparently even the Army went to 10 gauge adapters. http://bulletpicker.com/cartridge_-37mm-blank.html
The manual form which the info is from is from 1944. The adapters are available for the M203/37mm launchers. $35? Check out the 10 ga line throw H&R guns, are they special ammo or the "usual" 10 ga blank?

https://www.navalcompany.com/linegunaccessories.htm The Bridger line thrower, black powder cartridges, extra light, lite, or heavy loads.

https://www.rbgcannons.com/store/p9/Winchester_Black_Powder_Blanks.html 10 ga Winchester black powder blanks, $55/25. Gee, 8 dram equivalent, regular 12 ga are about 3 dram eq. I was expecting light loads for blanks. "Dram Equivalent" is the smokjeless powder conoarison to the drams of black powder, I guess those blanks have 8 drams of black powder? 220 grains of black powder? I think "BLACK POWDER ONLY" in your cannon? Since modern blanks as well as the old (up to WWII at least) were black powder.

What is the chamber length of your gun? Short I bet, can't put a full power anti-tank round in?

Pappy, you got me interested. And I've got 4 feet of 2" diameter bronze propeller shaft. Salute cannon here I come!

10 ga, because there is less chance of anybody having a projectile ammo around. A 1/4 turn interrupted screw thread like later Howitzers. Bottle shaped barrel like the Dahlgren 9 inch shell gun. Carriage can come later, I'm thinking steel ala WWI ?

I wonder if the back side of the tag would show a shadow of what used to be on the front? Held on by screws or rivets?
