When I was racing cotswold league at the turn of the century, Avon Valley Cyclery team (based in Bath) rode those.
If you phoned them there may be someone still at the shop that knows the history (IIRC they sold them in the shop)
So, guys from AVC lead me to believe these were made by Kinesis for them. After contacting Kinesis they made clear they never produced steel frames (they however still produce alu RaceliGHt and not Racelite frames). Dom from Kinesis UK says the Racelite frames were sold by Graham Weigh Cycles. After looking at couple of GW frames on forum I established all of them have similiar main triangle (very similiar if not the same to mine) and are branded with Reynold 853. Currently waitting for a response from GW to see if they had anything to do with these frames. This would certainly be a pleasent surprise, especially if it is a Donohue build. Attaching the pic again in the case someone knows something more on this topic. The project is now quite finished, just waitting for nice weather to take couple of nice shots!
