Larry, I think it IS Tommy Bullus. He was from Leeds, and didn't go into business with Bill Doran. That was Matt Wright (ex AJS mechanic), and they set up Doran and Wright in Whitchurch. I'm still in touch with Peggy Doran, her daughter Jayne, and HER daughter Emily who works for a Ducati shop.
Tommy Bullus worked for a local finance company Union Transport Finance (UTF) in Pudsey between Leeds and Bradford in the fifties.
I do know someone who could confirm the photo IS Tommy.
