Had a 1962 M151 with all the arctic stuff and what looked like the original
engine.
They were surplused en bloc in Alaska, and evidently shipped down to the
Pacific
Northwest by some salvage company. They still crop up from time-to-time,
and I've
personally come across four - all within the same range as my old beast,
2D-1753.
This is probably old hat, but the angle on the mounting brackets for the
rear suspension
on the 151 original model and the A1 model was different, and where the
original 151 rear
suspension had but a single rubber bump-stop to limit suspension travel,
the 151A1 had two.
The suspension arms are also supposed to be stronger on the A1 as opposed
to the
'straight' model, but I can't recall where I read that.

"Dual brake system"? Same master cyl on all variants, isn't it?
