Nice to see the set of four reproductions Gary. Expect you have got your 2013 Paisley, Ontario M-H Expo seat on order for collection in August?
Whilst talking about rproductions I got an email from a collector earlier in the year asking about M-H-F era cast iron seats, of which he had apparently purchased one in a collective auction.
My reaction was that cast iron seats were long out of fashion and too costly for production in the 1950's and offered my thoughts of it being a modern reproduction.
Early March at the Malvern indoor tractor show again in the Saturday auction another of these seats appeared, the design is very similar to lots of cast iron seats but when picked up it weighed almost double what an original of this style would, so confirmed to me it was a modern repro patterened off an old seat with lettering modification and cast in iron rather than alluminum like your set Gary or the Expo seats..
Has any of these been seen across the pond?
