Was that one of the aircraft from Ernie Simmons farm?
He had several along with Yales and IIRC, Lysanders.

I think many, perhaps most, of the surviving Bolingbrokes came from his group.

I think Ernie Simmons had only 1 Bolingbroke, you may be thinking of Wes Agnew of Brandon Manitoba who had many Bolingbrokes pass through his ownership over the years.
