Correction on the previous post. Seth Cole 55Y paper was used. This posting shows the modification to the loading ports to allow loading the paper cartridges. Metal must be removed from the loading port from lengthening the port and opening it on the top portion and removing metal from underneath the barrel. This can be determined by a bit of trial and error. Photo shows the cartridge interfering with the port and a cartridge loaded and positioned under the plunger. Work slow and trial fit and it is easily accomplished.[attachment=1320]

The Seth Cole 55Y gives the appearance of the combustible skin type cartridges used in some packets.
