Thanks for all your input so far,i have spent hours and hours on the web and have probably looked at every steel frame on Ebay for the last few months and zilch ! Measured the tubing and its not metric 531,the seat post size was measured by someone at work but i gave the seat tube a good clearing out and it takes a 26.8 post,blasting it has revealed nothing . Have put it next to my 82 Gran Sport ,note the bigger chain stays and the much slimmer seat stays on the mystery frame.Would love to find out what it is as its my size and looks like a good ride,would have thought the BB Shell might have jogged some memories.
