Removed everything from the frame, one of the easiest strip downs I've had yet, only the non drive side crank offered any kind of resistance but it eventually yielded once leverage was multiplied thanks to a length of pipe.
There was some light debris in the BB shell, but nothing to be concerned about, all threads are good, BB and headset are in excellent shape and after a clean will be going straight back on. I'm very pleased with the condition overall, lots and lots and lots of scratches but they are all paint deep only, no dents, dinks or even serious scuffs, the chain stay is perhaps the cleanest part of the entire frame thanks to the Stay-tuff strip.
I'm really hoping that after a thoroughly deep clean and some T-cutting the frame will be good enough to leave as is, I don't mind a little patina but if it looks too scruffy (as black tends to do when aged and scratched up) I'll go for a new paintjob.
It's going to be set up as a drop bar bikepacker with a mix of XT and DX, a Middleburn crankset, Wolber/DX wheels and racks front and back.
Edit - After doing some more research I'm beginning to think this is a Roughstuff and not a Black Leopard, the reasons being that the front forks are fairly narrow, 1.9's fit fine but it leaves no room for mud guards, plus it only has mounts for two bottles, it came with very narrow tyres (1.5's) and that might reflect the original set up.
The truth is I'll probably never know for sure, but my initial guess was based more on the colour than the features, and the more I look into it the more the features point towards it being a Roughstuff. Either way it's a lovely light British made off-road tourer made with fine fillet brazed steel.
