Just like my Northern Tool! You'll love it, believe me! Buy some C-Clamps, and stuff away! You can get a new 0-ring for the plunger at LEM, probably other places too. That's about the only replaceable part on it, otherwise it's built like a tank and as heavy as one too! if you need a 3/8" stuffing horn for sheep casings, you can get one at Butcher Packer for an F. Dyck stuffer (sp purposely).
