That looks like an Imperial. I have one, and yours looks identical. I believe the major differences are the bowl, the pump handle, and the wet/dry valve. The Imperial has a slightly larger bowel, a longer pump handle with a bend in it, and the wet/dry valve is foot operated. The Junior has a slightly smaller bowl, the pump handle is shorter with no bend, and the wet/dry valve is hand operated. Rebuild
kits are available (for now) and are the same for both models. It's a great head
and should outlast us and our boats. I prefer a head made of bronze. There is something a little discomforting about a head with a molded plastic base/pump assembly. I'm sure I'm over thinking things, but I envision the base breaking / failing when "under load" in a big sea. It's probably never happened in all of head history
, but I'll sleep better in any case.
