Hi, all - I'm just trying to MOT my '73 Sherpa T for a bit of pootling around in Dorset and the MOT tester has identified a few loose spokes. I think they'll tighten up fine but I've no idea what size of spoke key to buy - does anyone have an idea, please? Thanks & regards - Mike

Ask these people, very helpful and quick.

Sizes can vary so best to buy a spoke spanner with multiple sizes on it.

If the nipples are original, they may be the alloy type in which case be very careful when you try and tighten them. They can appear to be in good condition but one tweak of the spanner and they can break up if they have corroded. Best to apply penetrating oil and let it soak in for a while and also to apply heat if there is any resistance when you first attempt to turn them.

That's really helpful, thanks, guys - I'll give them a soaking in WD40 for a few days before I try to shift 'em!
