Gents, FWIW, I have a TriEx W-51 (laying in the yard, still) with the 
factory installed winch still mounted to it.  It's a worm gear driven hand 
winch made by a company called  'Valley.'  Google tells me that, likely, the 
manufacturer was a firm now known as Valley Industries.

I am ever so hopeful that the W-51, once it's in the air, with this Valley 
winch is easier to get up and down than my US Tower TX-455 with it's twin 
K-1550's.  Yikes!  The TX-455 is scheduled for a winch transplant (I bought 
a used Thern worm gear drive, heavy duty winch with a drill drive adaptor)
