Unknown cartridge - help


#1

Does anyone know what the attached cartridge is? There is no head stamp. I pictured it next to a 30-06 for size comparison. Trying to figure out what a lot of the antique cartridges I have are so I can list them as I have no interested in much of the stuff that is from the 1800s or early 1900s.

Might you have approximate dimensions of the cartridge?

Right off the bat, it looks as if it could be a 50/70 by U.M.C. . Specs, would be nice !! M rea
