As you suspected, it's a Uniglide freehub. The smallest sprocket threads on to hold the other five in place.
To remove it, you need two chainwhips: one to hold the cassette and the other to unscrew the smallest sprocket. If you don't have two chainwhips, there are ways of improvising as suggested above, or removal shouldn't cost more than a quid or so at your LBS.
The freehub body will take a 7-speed Uniglide cassette, or you can replace the body with a Hyperglide model. 7-speed Uniglide cassettes in suitable ratios are becoming quite rare.

Thanks for everyone's advice. I suspect it will mean a trip to the bike shop and an upgrade to a hyperglide body. Here's a couple of pics of the bike before I start any 'upgrades'. Twenty years ago I couldn't afford something like this but twenty years on, £31 was all that was required!!!

those wheels look older than the bike.
A recommended upgrade would be to fit a later freehub that accepts an 8 spd cassette. This combined with a set of 7+1 Deore DX thumbies gives you much more access to cheap spares and a wider range gearing.
You would have to get the wheel re-dished and the axle spacing changed to suit.
However, all of the above is pointless if, as I suspect, that axle is 130mm as opposed to the later 135mm standard.
If it is 130mm width, a cheap Deore 9spd hub will be a good donor for axle, spacers, and freehub.
Lots of beer, a sunny afternoon, a spoke key and some grease is all that is required

I've used them successfully too - (and let's be honest 'cos we've all done it, the hammer/screwdriver method) - but the handle on my oil filter wrench is short and needs a cheater bar for extra leverage.

I've no doubt the wheels are older than the frame. Looking at the gear and reading the correct spec for the bike on the Vintage Trek website I suspect this was bought as a frame and built up with a mish mash of parts. The frame itself is in very good nic so that's the important bit. As for the rest of the gear, I'll retain as much as is usable but some of the kit is beyond help so will be replaced. I'll post more pics when it's done. I'll also post some pics of the wife's Saracen Sahara which was another ebay bargain last year (£24) and has been brought back to life!!!
