Most agricultural dealers will find you something. Be prepared to know what gear ratio you want.

There's a place near Middlesbrough that advertises/sells on ebay winches similar to the photo you posted.

That looks like the worm drive gearbox off a roller blind door.

As above, gear ratios and gear type is important, go with worm drive because if it stalls  it’s a natural brake. Also worth looking at the clutched gear reduction engines, they give more grunt and you can use the throttle to stop/start the pull instead of running the engine at full chat all the time. I would also lay the reduction box flat so you get a centre pull rather than off the side, off the side like that will have it going squiffy on the pull.

Hi! Thanks for your reply! Whats a gear reduction engine? 
 

ive been using the winch for a few days and all was ok until we pulled some big oak! Think it must have stripped the teeth from the driven gear! Not sure what the gear ratio was as ive yet to find any data on the gearbox!! 
 

im going to replace it with a 100:1 drive and also get a new pully sorted thats flat rather than tapered as the rope keeps running over each other and wrapping up if you have a few coils on

I have welded a few bars on the front of the one I built to keep some direction of the rope on the drum, pull line always feeds into the lower part of the drum, two wraps comes out of the middle bar and four wraps over the top bar. Nothing ever gets tangled.
