David and Hanno,

I can confirm that SM 2561 are the half-tracked Snowmobiles made by "Bombardier Snowmobiles, Valcourt, Quebec".

The Vehicle Code for these were: BHT 8 - SNOW - 1

I have found some pics I have of one of them still in running condition (sligthly modified), but I only have the negatives left. I will try to scan the negatives - otherwise I will have to make new paper copies. I will also look through some books to see if I can find pics of them in civilian use in Norway.

From the data plate:

VEHICLE CODE BHT 8 - SNOW - 1
CHASSIS SERIAL DND 100 - 80
ENGINE SERIAL 3 G - 39552 F
TRANSMISSION SERIAL Z 23873
ORDER NO SM 2561
DATE OF MFG 10 - 15 - 42

The owner of this one have two, the other one have CHASSIS SERIAL DND 100 - 81 and DATE OF MFG 10 - 16 - 42 (I don't have more information for that vehicle as I have never seen it - but I will see if I can manage to take some photos the next time I am up where they are located).
