I went to look at MASH before getting the Bullet. The ones I saw at Haywards of Cambridge, unregistered, were rotting where they stood. Spokes, welds round the footpegs and headstock, all looked like something that'd done three or four Elefant rallies without a wash. A great pity, but IMHO the Chinese aren't ready yet. I've given the Enfield the full ACF-50 treatment in the expectation its no better, but starting clear of rot has to be better even if only because they keep the crates dry on the boat.
No idea on SWM, the urge to buy and a dealer 4 miles away got the better of me before I went to see one.
