It's a Chelsea 352 from what I understand. See the bottom of the page
here for a smidge more information. That's a combo I'd like to put together myself eventually, so I'd definitely be interested in seeing it done.
A PTO hydraulic is definitely the fastest possible winch combo I've seen ... talked to one guy with a 20gpm pump who timed and scaled his to 20 feet per minute at over 9,000lb with a very similar setup. Unfortunately he was running his PTO on an NP205 because he didn't have a manual with a PTO port, so he had to run in fourth gear with the TC in neutral to get those numbers, not a very good combo. An NP435 shouldn't have that problem, you should be able to use the winch in gear and get good line speed.
