Thank you for the wagon photographs Alan, I have yet to see a wagon reach plate with M-H on it, my three M-H wagons have the plain ones like Gary posted. strange when Bain were so proud to cast their name into the plate.
Sorry to hear your pitman is not going to fit your 734 mower, but as you say it will display well in your growing memorabilia collection.
Earlier you mentioned the power units on the Sunshine stripper headers we have seen on our travels, well I am so sorry to tell you unfortunately they were built around the "Fordson" tractor, it is hard to say that word on here Alan, especially as you know what my dad's favourite saying was for those old tractors!!!!!
Anyway despite all that the self propelled Sunshine headers were certainly ahead of their time and I bet an experience to start, operate and maintain.
