So we have another what appears to be Canadian cover (as it is addressed to Canada) with a US postage stamp to pay for the 6c air mail rate - see John Cranmer's cover under "How to understand this WW2 cover and letter" posted on 11 January 2021.
FPO 118 was allocated to APO S.479 under 7 L of C Postal Unit on 14/4/44 and was still shown as being with 7 L of C PU on 6/8/44.
Proud shows this as Bizerta, Tunisia (31/3/43 - 17/3/44).
I am sure that I have seen this type of censor cachet before - but where I cannot remember!
Mike :)
