Hi i was just looking for a little help identifying an old lightweight frame i picked up years ago at the local tip.
It is very light (lighter than any 531 frame i remeber) and has unusualy thin rear stays.The steerer tube on the forks is marked as ackles and pollock so i guess the whole frame is ?
The bottom bracket shell is rgf but i dont have a clue about the rear dropouts altough they are quite distinctive.
There is a braze on for only one gear lever and it looks a little shorter that the ones you normally find.
The threads are english and the number 1003 is stamped on the bottom bracket shell.
