British Bulldog crash in the Brisbane Ranges NP

I’m chasing up some information about a plane that crashed in the Brisbane Ranges in 1936 (a British Bulldog). I did receive some contact from Mark (?) about the crash site but I have lost his  contact details. (I’ve had serious medical issues since Dec 2019 and I’m just getting back into doing things again). He said he would call me again when he was free to come out to the park and show me the location, but we’ve obviously had some lockdown issues to contend with. If Mark or anyone else has information about this crash I’d be interested. The Friends Group would be interested in making an interpretation sign for the site to explain an interesting piece of local history.
