I am quietly listening to all that is being said. All I can personally tell you is that the frame and forks were purchased from Overburys in Bristol, of that I am certain.I lived in Bath at the time. It was purchased and put together by an old boyfriend who was a massive bike fan ( at the time he had a couple of Rocky Mountains which I think he had imported and an Alpinestars bike)
He put it together for me because he had plonked me on the Alpinestars bike and it was treacherously too big!
If this bike was repaired in any way... it was not since I have had it (1991) I have no recollection of it having been repaired prior to purchase either... I am pretty sure I would know if that was the case. But hey... we are talking 20 odd years ago! As there is no way of contacting Mr P it seems, I have taken it upon myself to try and contact the guy that put it together for me. He probably would be as fascinated by this story as any of you! If I hear anything back I will let you know. Similarly once I have had some professional eyes look at the frame I shall let you know.
To be fair to you, i think we all want it to be in good shape, original and not repaired. These are sought after as you can probably see.
I know it was 20 odd years ago, but can you remember why the front fork is in the original colour whilst the frame is different/purple...?
Could you take some better pics for us all, this may help, all the suppostion is based merely on a single picture.
