Here are a few detailed photos of the punt gun. Any suggestions re it's maker would be of great interest. It weighs in at just under 1 cwt, 9 ft long, 1 13/16" at the muzzel and 2" chamber. I had 3 cartridges made. Using what information I could find and using the old formula of 1 oz of shot 6 lb of gun I use 18 oz of shot and use the same measure for the coarse black powder - which works out at around 3 oz.
The chamber has a 10 thou taper and the dovetail for the cartridge head has a 5 thou taper to aid easy loading. From the chamber taper we assumed it was made for a brass cartridge rather than a paper one - they seem to work OK. I use a .38sp case loaded with fine BP to act as the primer - it has never failed to fire first time as yet. It is non rebounding so you have to half cock the cocking leaver to insert or remove the cartridge. The barrel is covered in shrunk on canvas painted grey - I guess to protect it from the salt It's a great bit of fun.
