Nice work -- how about an end shot in the big end or more details -- i.e. thickness of brass sheet, lap or butt joint, soft or silver solder/braze. How do you plan on attaching it to a horn?Many years back I made a few of the English Shot Flask charger head that has a quick cut-off gate and that was a chore to get it working properly also made them for powder dispensing. All were a lot of work for little return.
Some better looking ones.
