Many, many thanks for your advice and opinions.

The frame and fork was made by Roy Thame in London during the 70's. There is a partially readable serial on the BB shell but nothing but an oval stamp on the steerer tube. Does anyone have any info. regarding the dating of Roy Thame frames. I also would like to find out what model it is.
I previously created a thread in Vintage bike subforum but that didn't really get me any answers.
