A new private message reply from SteveW.
Just got a look at my windlass. The plate is almost unreadable but I can just about make out the specs on the motor using your plate for comparison and the motors do seem to have the same specs. If it is not too much trouble, and you can find the time, I would be grateful if you could do a measured pull test. Mine comes out at 30Kgf.

Is the challenger mainsheet windlass still available?
