Well, finally I obtained the copy of the Flypast Magazine (thanks a lot all involved!). A map was in the magazine, and its source was an official map from 49 EOD Sqn Det (RE). The Puma was located NW of Lively.
Also, I have a copy of DEFE 48/1169 (Reconstruction of the air war during Op Corporate) and, again: Lively.
Keep searching!
