Fast jet friend used to rally one in the RAF, would have been in the late 60s(?) He also commented on the ease of rolling them and the weak back diff.
I bought one in 69 for £45 (I was rooked!) to retrieve a boat from the SOF. Did about 9mpg, but towed well. Nice, if heavy, steering. Would do 95 flat out with the screen down and even London Taxis respected it.
