Bit of a long shot I know but does anyone on here own, or know of someone who does, an exceptionally well built red Briesch Lil Brother engine built by a British ex aero engineer called Bill Linfield ? He would have bought it from Bill's widow about 5 years ago. Reason I'm asking is that I also bought one of Bill's engines, a Wyvern, and only just now discovered that I have loads of pictures detailing the build of the Lil Brother at every stage, about 50 in total, really nice pictures and worth having if you own this engine. It seems that Bill was also a keen photographer, all the pictures have their negatives with them. I will send to whoever owns this engine if I can find him.
