Thanks again guys. Purple, don't go to the trouble of stripdown yet, I'll contact Fibre-Lyte and see what they say as Terry suggested.
Terry, did you use to work with Derek in Stockport Model Shop years ago and go racing at Cheadle Drill Hall, I used to go there when I was a wee nipper! Thanks for your offer on the fibreglass replacement, I do have access to AutoCAD so can draw in DXF format. I am thinking now I could butcher a template out of paper/card and then draw it up on CAD from that, then either get it done in fibreglass or aluminium. Terry if you do have any other bits it'd be of interest as I am thinking of trying to race it next season rather than shelve it as an ornament, to see if I can give these upstarts with their B44's a run for their money!
Things are looking up, cheers for your trouble guys.
Chris
