Do you have a frame number for this EH. I ask as I am trying to establish what the frame number sequence was. Mine has 2 numbers on both the bottom bracket and fork tube. I have a suspicion that one was applied by the maker of the frame (maybe Holmes of Welling ? ) the other by the shop
Numbers are : 626 (makers number ?) & 444 (EH number ?) Pure conjecture this but I am aware of another frame of similar date to mine which carries a much higher number (over 1000) which would indicate production of over 250 frames p a which makes no sense. Had there been that many E Hamilton / Lorraine Cycles sold there would be far more still out there.
