Thanks sprocket, I think from looking you have nailed it. I did think maybe a Excelsior only because I have a old Excelsior Autobyk and it seems these were also only done in a black and white. As for the reg No, I have no idea how old reg No were worked outs so as said it looks like sometime between 27 and 31 and if the Excelsior was around 29 then the photo must be then or sometime after that. As long as its not 1927 then thats OK with me. Cheers, Jon
