Well, that's a relief to know, as I am feeling a complete fool.
I owe an apology to all, especially Brucey, who rightly suspected the part to be an Altus freehub from the start.
Somehow or other - perhaps early onset going gaga - I have confused my Marin MTB with my daughter's Trek hybrid. I was absolutely sure that the Marin had a freewheel and the much newer Trek had a freehub, as I had checked them over and re-greased both only a few months ago and I have bought a Sram 12-32T seven-speed cassette and a new seven-speed freewheel to fit at some point.
In fact, I have confused the two bikes.
On road bikes, you can tell a freehub and a freewheel at a glance, but these MTB / hybrid frames obscure the gears. When I eased the Marin wheel out to address Brucey's query above, I was appalled to see at once that it was a freehub after all and that this entire thread was based on error.
But the advice given above has not been wasted, because console yourselves ...
It looks like I am going to be £150 out of pocket, as I am waiting delivery of the SLX hubs off eBay and rims off Spa and have yet to order the spokes.
All in all, though, perhaps this is not really such a bad thing. The existing wheels are 25 years old minimum, the rims are not double wall and I have no idea what use they have had. If I was pottering from home, I would leave them as they are until they broke. But for a significant tour, it makes sense to upgrade even if the reasons are different.
On reflection, I am not sure Roger Musson would be too pleased to see that I had described myself above as one of his students ...
