Welcome to the forum Richard, and a very interesting bike you have there!! sorry I cant help personally with any photo's but I do remember the bike and I'm sure many forum members including myself would be interested to know more about the project, where did it turn up? where has it been for all these years?
I was a neighbour of Roger Marshall during that era, and as I'm sure you are aware in his early days Roger was mentored by Steve, I remember him having Steve's TR3 for the 1973 season which Steve had ridden in 1972, so I reckon Steve would last have ridden the TR2B in 1971, maybe into early 1972?
Hopefully someone on here will turn up some photo's but meantime you could also try dropping a line to Malcolm Wheeler at Morton's who produce Classic Racer magazine as they have a pretty extensive archive of photo's and might be able to help.
Good luck with the search and please keep us posted as you continue the build.
