Canadian NSN Catalog

[Ed Storey]

Yes, there was a huge amount of new material introduced during the war that did not get catalogued until after the conflict was over. You have to look into the wartime Army and Routine Orders to keep up as new material and changes were at times recorded in those documents. Looking at wartime British vocubularies, even if an item is listed, without an image, the description can be vague or misleading.

I always wondered why the electronic versions of the CGCM and CGCS did not include a photo of each item. It would save millions in not ordering the wrong part. There is/was a way to search the part number thru the EIF catalogue and that would hopefully get you to the illustration in the part catalogue. They also use Equipment Reference numbers (ERN) which will tell you what equipment the part or bolt is used on, and you can then work backwards to figure it out. For instance, if the ERNs for a headlight was 30350, 30460 and 30105, you could search the MLVW, the 5 ton, and the M151A2 manual for a line drawing.
