WW2 Redirected Cover To A9958 Raf APO 5095 ?

I have just got this cover principally for the two handstamps on the reverse. The cover is addressed to a Canadian, possible named Pilot Officer J. V. Manzerolle service number J17430 originally with 296 squadron - an airborne forces squadron



But I am curious about the redirection on the front that I cannot decipher.



The red pencil reads A9958 RAF APO 5095. and there is a circled 326 which is probably? his new squadron. 326 - a Free French fighter squadron - was not formed until December 1943 which is after the dates of the handstamps on the reverse. The original date of posting is not readable. 326 was formed by the "take over" of the French unit GC/II/7 "Nice" which had taken place in April 43 with the official name change in December.

The letter was sent by Adrienne Mazerolle ? so the connection with a French squadron makes sense.

Any suggestions are most welcome. I will also look at the relevant ORBs when I have time. I have not found anything about APO 5095 yet.

The 326 could be referencing the USAF 326 Bombardment Squadron.
