Hi, there's some info on Birmingham Sun's scattered around the web, basically they were a good medium sized builder, who peaked in the late 30's thru to early 50's, after that there was a slow decline until the Raleigh takeover in 1961 'ish. The superlite name was used during the fifties, so to start with, piccies would be useful to identify, and there should be a serial number on one of the dropouts, can you get this and we can get an idea of the year.
