2pdr gun
« on: March 20, 2013, 01:33:08 AM »

Going from one of the largest patterns of British guns to one which is both unique and one of the smallest in the collection we have. This gun has a bore of 2.545 inches, which equates to a calibre of 2pdr and is a smooth bore breech loading gun designed by Mr J C Daniells and dates from 1807 and is 38 inches long. This design seems to never to have been adopted for service use and has spent much of its life as a musuem piece.
The carriage is of a rear chock design and seems to be very old, possibly original and unique to this gun.
 
I had to edit this post as I realised I had attached the wrong picture at the time sorry all.

I've never seen this one before but I'll try to guess at how it was itended to work.  The op handle is pushed forward which by a linkage under the barrel, tips the breech up, muzzle down.  There's a breechbock attached to the carriage, and when the breech rises, the bore or chamber is uncovered since the breech is pulled off of it.  Gun is loaded thru open breech, lever pulled back, breech drops down over breechblock, etc.  A possibility anyway.

Very close,
The lever on the side operates the elevation.

The actual breech is worked by the lever below the barrel.

I'm thinking the breech block must be slightly wedge shaped to obtain some degree of seal...

Very interesting design basicly a sharps rifle on steriods... the block may not be tapered it would interfere with lock up as it got grimed up with black powder residue depending on how the cartridge was made it may have worked as a gas check against the breech.... the British military had a Monkeytail carbine it's cartidge had a felt pad at the rear it acted as a gas seal and it was pushed ahead of the next cartridge when loaded.... this may have had a simular set up....

True, there looks to be some evidence on the breech block lever of some pursuasion being used to open the breech but it would have been hard to apply additional force to close it.
