A few years a ago i had a JW frame and contacted M Steel [as it was made a few back before DY set up his business in Lincolnshire] to find out what tubing my frame was made from and was told there was a flood in the factory a few years before. As a consequence, they could not tell me what tubing my frame was built with and that will go for this frame too.
The key factor is the seatpost diameter if it 27.2mm then it will most definitely 531DB/531c or above and i doubt JW frames were ever built with anything less.
A lovely frame by the way and i like JW frames and would be my size too.....price is fair but a tad high for me.
