We had the same model as this Darren at home, bought in 1990. Ours also had a red uppy downy spin speed selector but apart from that it was identical. Have to say was not a fantastic machine for us, the dryer fan kept jamming, it needed tons of new damper pads, at least one new programmer, and probably tons of other stuff.
There was no OOB protection, Rob, though ours never moved an inch TBH, my guess is that mb there were other issues with your mate's machine, perhaps the concrete had gone anyway, or it wasn't level or something.....
I didn't actually like the machine much, I just didn't connect with it. But that's just me! They were certainly great at washing - good results . Should be noted that ours, as Darren's, was not a jetsyetem but was a turbo dry.
