I may have to strip the bike anyways as it is in need of a service, So pricewise what would be expected for the groupset, wheels frame etc??
Pretty hard to give an accurate valutation on older bike parts. Two identical parts may sell for wildly different amounts depending on who wants what on any given day. If you want an idea my suggestion would be to search through the for sale forum here or the completed sales on ebay. As I said before I reckon you might see £1K out of that lot there. F+F maybe £300-£400. Some of the record parts can fetch around £100 like the shifter, calipers, chainset and rear gear.
