The model is the Head Mate, still available from WC, see their web site.
Not sure how compatible their current rebuild kits are for the models dating
back to
1979 but I did replace a 1980 CS27 head with a new off-the-shelf WC Head
Mate
this summer, it was virtually part by part compatible on the outside, did
not disect it.

I'm going to have to put a rebuild kit in the head on my 1979 CS27. It has
a
Wilcox-Crittendon unit that looks like it was OE, but there is no
indication
of the model, so I can't tell which kit to get, or even whether a kit is
available for it. Can you give me a clue as to how to tell?
