Also, i have never heard of the 411 being fitted with the frog eye cab, as far as i am aware, it was only ever fitted to the 401 and 402? the only westfalia cabs i am aware that were fitted to the 411 were this one, the u32 had the cab designation 117 and the u34 had 120? for example, mine is a u34, and so has a chassis number starting with 411 120.
