Here I am,
Thank you for the further informations,
I add the following serials:
Dashboard serial,
Engine serial,
Ziebart tag serial.....
I can guess that the engine is not the original one, same concern about the windshield but I hope the dash is the original one,
for the moment i didn't find more codes or Tac Signs.
These M151a2 were cut and welded taking care of rejoining the matching bumpers serials from Perini of Riva del Garda.

I have reports that the non matching numbers have been sold painted USARMY olive green or USARMY/USMC camo colors,

other matching serials have been repainted from the owners as USA M151

being difficult to find original CDN uniforms.

I am proud to have a CDN one!
