Dont know anything about them as a frame builder but I saw that frame on ebay.
If those pics are of the ebay one it looked completely fillet brazed and very similar to my Overbury's in design, wavy seat stays, no chain stay bridge, same cable arrangement. Only difference was the seat tube clamp position.
Mine was dated by Andy POWELL at around 97.
The only Dave Hinde frames I have seen in the past were aluminium and I assumed rebaged far east jobs.
Any chance they got the steel ones built "out of house" too and rebadged them?
