Photo's of Bottom Bracket, headtube, dropouts, fork crown, rear brake bridge, seatpost clamp area. Frame number and whether the frame number is repeated on the steerer tube. These are all essential for an accurate ID where no decals or headtube badge are in place. Was the headtube badge rivetted or a stick on? Is the bottom bracket shrouded at each end or bare? Always willing to spend time on identification but need all the above to go on. Should also say I don't do "I thinks". Positive ID only or an honest don't know.
