The RCAF was amalgamated in 1968 so the ****ehawk could as easily been liberated as a "trophy" by an RAF detachment to Canada to accompany ships' name plates and army field guns that adorn crew rooms here in the U.K.
I remember kidnapping the Chinth, a temple lion and badge of 435 Sqn RCAF in the 70s from their base in Namao. It was returned on a Cross Check Exercise with its progeny, a Thinch from an encounter with one of our badge animals.
