WoW, good find DD bro. This seems to be 406 short-bed. I think this was probably not the only one, this picture has ignited the old memories, reminds me of a snow blower used to work in Muree/Galliat in early 90s.
I am just thinking that in that era what other vehicle could have been used by our municipal for this job? And if my guess is right then the Orange Unimog spotted in I-9 was surely one of them!
