Wilcox Crittenden 51 Type?

So… I know this has been asked before, but it gets a little confusing. I have at least a partial ID on the head in our new(to us) Cheoy Lee Offshore 32. The casting says it's a Wilcox Crittenden 51 Type … the last part of the casting is just too worn to really make it out with some assurance. I'm pretty sure from all of the searching I've done that it's a Junior or Imperial.

What are the practical differences between the two? Aside from cost, I'd hate to order the parts kits(which seem to be readily available at least at the moment) and lose another week or two after realizing I don't have the right stuff.

New to posting here, but I'm going to try and include some pictures.

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.

Salty, just wanted to say a (belated) thanks for the info. I just got a rebuild kit from Defender. A few other projects are higher on the list, but I'm sure the admiral will move it up the list pretty fast!
