Thanks all for your replies! I won't break into the box then, I just wanted to see what state it was in but the half that opens looks to be in great condition - I'll leave it alone. I do have some major snags with my C5, for example, no battery, broken chain, no inner tubes, perished tyres, missing handle bar cover, hole in the floor by my left foot, missing front left indicator, lots of rust, some wires cut and a junction block used to join others - surely not originally joined like that? And so on... Cheers for now, Dave
