Update on this. Following a year that was total Excrement, including be off ill for a lot of it, but that's another story. The trailer has been cleaned patched and painted. Only serious work was to repair one wheel rim. The construction is massive! All the chassis and running gear is excelent and brakes just needed cleaning up to work fine. Two ex Landy 600.16 tyres scourced and look the part, originals had rotted away. Took it out for a test tow last week, perfect! So decided to fit one the pumps, took two of us, a winch and engine lift, those things are heavy! Then towed it about 60 miles round trip no problem. Work has started on pump, Data plate shows re-con in 1961, 10 thou over size rings and crank bearings. Oil is clean and engine turns smoothly. Next step strip and check carb them magneto. Points and condenser are suspect but we have spares so should be able to build one that works. It is now tucked up ina garge for winter , so at least undercover to work on.
