(Synopsis needed)

Season One

De Havilland DH82A Tiger Moth

Episode 1.03 The Green Mill Murder.
Reg. VH-PSD De Havilland Australia DH-82A Tiger Moth c/n DHA806 /T022 built in 1942.
First registered as A17-656 for RAAF, then VH-AXU & VH-RSD on the civil registry.

Season Three

Sopwith F.1 Camel

Episode 3.02 Murder & the Maiden.
First, some GCI featuring the Sopwith Camel (perhaps the replica built in 1974- of The National Museum of the U.S. Air Force, Wright-Patterson AFB, Ohio). Seen again in the movie Miss Fisher and the Crypt of Tears.

Sopwith Pup

Episode 3.02 Murder & the Maiden.
Sopwith ! it's written on the tail ...
Probably the Pup of the Fleet Air Arm Museum (New South Wales, Australia). If yes, he can't fly as he's displayed with the extrados of right low wing without covering.

De Havilland DH82A Tiger Moth

Episode 3.02 Murder & the Maiden.
First a crashed one (but just a pixelized one).

Reg. VH-LJM De Havilland DH82A Tiger Moth c/n DHA996 built in 1942. Coded A17-561, she is only seen on the ground.

Code A17-561 is guessed by the top of the last three digits between yellow ring and the roundel.

But this one devoid of any markings makes the action !

Episode 3.08 Death Do Us Part.
Same aircraft seen at the end of Ep. 3.02 ?

Ornithopter

Episode 3.02 Murder & the Maiden.
Some memory and historical machines including an ornithopter project between the two actors.

Airco DH.16

Episode 3.02 Murder & the Maiden.
Reg. C-AUF? doesn't exist during the 1920s; it could be G-AUF? but it seems the registry didn't go so far before the World War Two.
