I have in my posession what i believe to be a series 3 swb ex army canvass top, is there any way of identifying it more substantially ?? I took it from work (with permission) as i found it tucked away in a box at Ashchurch (military vehicle storage depot) and it was just going to be chucked away, it appears to be brand new, it still has the wax coating on it. There are no poles or anything but if anybody is interested pm or e-mail me, cheers, p.s: how much are they worth out of interest ??
