Have spent day with AZ boys (and girls) at John Mould's collection in Reading. Will set up a new thread on that.
Back to the point, 30 years of scrabbling around in the farmyards and hedgerows of East Anglia has only produced these two manifolds which might be G28. What do you think Derek (or others)?
What is the record for (piston engined) paraffin/kerosene power at Bonneville by the way?
