- [O.K. this is a little off of our normal topics, but Mr. Moderator, you
- MADE me do it - you're the one who keeps saying "buy 'em all"]
- [MODERATOR: But I will disavow any knowledge of having said
- such a thing should some angry spouse ever approach me with
- complaints about running up too big a Visa bill....]
-
- A strange ad in our local _Thrifty Nickle_ led to my buying myself
- another gun, but I'm not sure just what I bought!
-
- The ad read "Antique Naval Cannon", and when I went to look at it, I
- couldn't help myself, so now it's sitting in our entryway. Now I need
- figure out what it is. Anyone who can help, please E-mail responses and
- I'll summarize to the net later.
-
- The gun and mount are apparently constructed of naval bronze, with a
- barrel about 30" in total length. The gun and mount probably weigh about
- 100 lbs or more. The muzzle end is about 3 3/4" diameter, with about a
- 2 3/4" bore. The other end is about 5 1/2" in diameter, and is cylindrical
- for about 9" until reaching a wide "band" which also has large cylindrical
- mounting studs projecting on either side. This all is mounted on a base
- unit which also appears to be bronze, which allows the gun to be pivoted
- from almost horizontal to 45 degrees up or more. The elevation is adjusted
- by a linkage pivoting off the rear of the barrel and held by a large pin
- which can go through any one of seven holes, so there are only seven
- discrete elevations for firing. The mounting is marked "C. C. GALBRAITH
- & SONS, NEW YORK, U.S.A.". There are no other markings anywhere on the
- mount or the gun. The forward 19" piece of the barrel unscrews from the
- breech part just forward of the pivot pins, revealing some unusual design
- features. The bronze breech part was apparently cast around a steel or
- iron chamber. This starts 3" back from the barrel threads and has a bore
- of approximately 1 7/8", which extends about 8 1/2" back towards the rear,
- and the touchhole can be seen near the very rear. Unfortunately, the
- touchhole area on the exterior is occupied by a large, apparently bronze,
- hex-headed bolt, which has a large peened depression in the center, so I'm
- not sure whether the touchhole went through this bolt and was simply peened
- shut, or if the bolt was installed to block the touchhole. The forward part
- of the barrel is bored larger than the 2 3/4" muzzle diameter, up to a point
- 3 1/2" short of the actual muzzle. This bored-out section is currently
- occupied by a piece of lead pipe, which I suspect was a later addition for
- unknown purposes (The inside of the lead pipe is covered with very yellow
- aged newsprint, printed with chinese characters - go figure?). It appears
- that there should be a longer (steel?) sleeve in the barrel which would be
- screwed up tight against the chamber section when the outer bronze barrel
- was screwed into the mounting band/breech section.
- Given the mounting with it's seven discrete elevations and the strange
- chamber/removable barrel/sleeve arrangement, I'm guessing that this might be
- a naval "line-firing" gun - one of the guns that would be carried out onto
- the deck, when necessary, for firing a line over to another ship.
- Any help in identifying this little bronze beauty would be gratefully
- appreciated. If anyone has any pointers towards good books about historical
- naval weaponry, that would also be appreciated. If I can't figure out what
- this is and how to fire* it, I may have to put it on the Suburban as a hood
- ornament ;-}.

- * I'm not really (too) interested in firing projectiles with this, but
- it would be fun to be able to fire off a blank charge on appropriate
- occasions. If anyone has experience with firing blank charges in a
- small cannon like this, please E-mail details or a pointer to books
- on the subject.
