I believe she carried the civil registration of VR796 - CF-HML and was operated by Spartan. It is now CF-HMJ.
She is a B35 Bomber. Similar to a B.XVI except for Merlin 114 engines in early versions, Merlin 114A engines in later versions. 274 built, including 65 by Airspeed Ltd.
Yep, she is indeed an ex-Spartan machine. I understand they tried hard to get the old HML registration reinstated but Transport Canada wouldn't give it to them as another aircraft now has it.
