Interesting discussion lads. Since the stanchions are cradles, it should be easy enough to produce a fold up etch, one would have thought, that sits on the wagon, ala the prototype. The end ones just have some extra steel and the upright end panel and ladder. I'd imagine they could fit on the SSM 42' or a KFA to suit, until a 62'9" comes along... Weshty?....?...
