Hi there,
I was just browsing and noticed your DB frame query.
Ok, what you have there is a 1983 full Chromo frame (early CRMO stamp of late 1983). It was originally developed and used as the Silver Streak replacement (a real shambles by all accounts). It would originally have been decalled up as a Silver Streak, but was dropped almost immediately and called a 'Super Streak' within the dealer network.
They are rare framesets but I think the forks might be a little later (1984/1985) but the correct design. daumenhoch
You also come across the same frameset starting F3 but stamped 500 (early Pacer 500 replacement) or F4 or F5 (500 and CRMO) as the same frame was used for a variety of models.
You can see my overview here about this early frame

Hi Steve,
Well, it's original that's for sure, as what to do with it, that's something only you can decide, but as far as a DB fanatic I would restore it how it was originally built, a Silver Streak 2nd Gen late 1983 (regardless of whether it was a flop).
Though the parts will be a little different to the original one. Mark @
www.retrospectBMX.com has repros decals which were re-mastered from my originals.
If you need any help with parts spec, just let me know. Smiley
I've also been offered a couple of Silver Streaks, just waiting on some prices and pictures. daumenhoch
All the best
Mark
