Hello everyone
I don't want to do the nonbeliever, but is that sure than M.A.C. is an english manufacturer?
I always thought he was canadian. I say that because on all cases M.A.C. ( or M.A.C.N. ) I have there is the broad arrow inside a C, as on the others canadian cases.
For me, M.A.C. is part of a group of canadian manufacturers, whose use what I name a system of alphabets to number the lots. If I am right, the first lot is 1-A, the second 1-B, when the first alphabet is ended by 1-Z the following is 2-A....
In this group, I know CC&F, CPR, DCPC, MAC and MLW.
Moreover, I think that DCPC had succeded to MAC in 1917. The cases of DCPC, I ever seen, are dated 1917 with very high lot's number, and MAC deseappears in 1917.
I have:
18PrII MAC.N 277-S (2-12-16)
MAC 286-J (15-11-16)
DCPC ( with EOB above) 301-N (2-4-17)
4.5 IN II MAC 99-W (23-1-17)
DCPC 144-D (14-5-17)
Note the letters B.A. above the date on the two 4.5 IN.
If anybody has an example which permitts to compress the bracket between MAC and DCPC, I will be very glad to know it.
Regards
