Unknown Coat of Arms on No. 15 Transit Chest

[tj214]

(Also posted in Vintage Military Gear forum--hope this is OK)

Just bought an original No. 15 Transit Chest out of Canada that has a severely damaged large paper label glued to the exterior lid, which I assume is a postwar and possibly civilian addition. The label includes this crest, which I cannot identify using Google Image Search. Anybody know what it's for?



Based on the standard contents label inside the lid, I believe this is a 1944 chest:

(19964) 43183* 9055 10,000 1/44 K.H.K. Gp. 8/8.

* Probably correct, but possibly 45183
