I know what you have now!
It was indeed made by W-C....here's what Jocko sent me:
Actually there were 2 units that were designed and engineered by Wilcox Crittenden during the period the company was owned/managed by Gulf & Western--
The "ELECTRA-HEAD-MATE" and the "EL-SEACLO" -
The electric HEAD-MATE was designed to attach to the Head-Mate waste arm - with an electric motor bolted down where the pump unit attached w/4 bolts
The "EL-SEACLO" (electric SKIPPER model) was a unit that could attach at the front of the manual unit and could be electric or manual - the foot pedal controlled the intake water flow
Yours is the Electra-HeadMate. The electric pump actually replaced the manual Headmate pump...the only comparable replacement today is the Jabsco 29200 "conversion," which I wouldn't have as a gift because it draws a whopping 25 amps (compared to 15 for most other sea water macerating toilets), makes enough noise to wake the dead, "chokes" on flushes that any decent MANUAL toilet, much less any other electric, could swallow easily...and has a trouble-free lifespan of about 2 years, if that long.
The motor only replaced the pump HANDLE on the electric Skipper...there are still two toilets today that are comparable--the Raritan PHE II and the Groco electric Model K. You don't want either one of those either.
If you want the "push button convenience" of an electric toilet, bite the bullet and buy a toilet that was designed to BE an electric toilet from the ground up, not a "conversion" from a manual toilet. Practical Sailor just published a test of all the most widely used electric toilets...they rated the Raritan SeaEra "best budget buy."
Raritan Sea Era It's available as either a complete toilet or a "conversion"...in this case, conversion doesn't actually "convert" anything, it only means you get to recycle the bowl, seat and lid from your old toilet, which saves quite a bit of money.
If your budget isn't big enough for electric, you would not regret going with the Raritan PH II/PHC rated the best manual toilet in its class for nearly 3 decades.
Raritan PH II Also available as a complete toilet or a "conversion" Check that out here:

You can bronze the W-C pump and display it as a genuine antique! :dance:
