The M-8 was standardized on March 1, 1943. The retaining spring was applied in Novermber, 1943 to both the M-7 and M-8 launchers. So I would think 1943 cartridges should be first year.
I went out looking into the garage this morning and found this Army Service Forces catalog dated August 17, 1944. I aquired it about 25 years ago. It's 8 1/2" x 5 1/2", 28 pages. ORD 9 SNL B-39 It shows the M1, M2, M7, & M8. It also shows Stock No., Drawing No., Nomenclature, etc for each. I thought it was an interesting read, so I made a few "copies" back then.
