Okay, following on from this THREAD
Here's all the info I've got so far:
"I’ll check about the BX, but I think it is away, he was taking the bits off it for me last week just before it was going to the crusher, but I’ll give him a ring and confirm,"
"The BX guy is an old friend of Graham Harper – the chap who looks after mine - he is Donald McLean 0131 553 5141 feel free to give him a call, I’ll report back when I have spoken to him,"
"Oh, I did ring the BX man in Edinburgh, but just got an answer machine."
So it may/may not have parts available.
