The Ongoing Mystery Aircraft Thread Part Deux.

And I was beginning to think that, with the depth and breadth of the knowledge assembled here, I'd never put in another appearance! So thank you, Mike. And here's a period piece, which I don't think has been used here hitherto, to take us on .....

 
May I put my guess on the Guerchais-Roche T5.0 ?

You may put your guess, sir, and if you do so, it will be an accurate guess! It's one of the two Guerchais-Roches produced for the French Air Ministry in 1931.

I haven't been able to find a registration for the T5.0 but the other (the T5.1) was F-AJHD. I don't think wikipedia carries any mention of the T5.0 and I didn't find any images of it online.

Sadly the Air Ministry were not impressed with either the T5.0 or the T5.1 - and so there their story ended.

Next challenge from Germany, please.
 
Salut Pomme Homme, it seems that we have the same source.

May I declare “Floater Time”?

Here is an according interesting number. Sorry for the grainy pic.

You should have a close look at the floats! These are carved after a historic and world-famous plane. The rest of the present vehicle was built from scratch to test these floats as a first step towards creating a flying replica of the historic airplane. Power comes from two Chrysler engines.
 
OK, more than 48 hours is enough.

From Jane's All the World's Aircraft 1985-86:

FLIGHT DYNAMICS INC, PO Box 5070, State University Station, Raleigh, North Carolina 27650

This company has test flown a single-seat twin-engined seaplane intended as a test vehicle for components of a replica of the Supermarine S.6 Schneider Trophy seaplane.

A constant chord wing of 10.6 m span and 13.28 m[SUP]2[/SUP] area is constructed from Klégécel spars with Iinear glass spar caps, foam ribs and glassfibre epoxy skin. Aerofoil section is GAW-2 Rectangular. Power plant is two 6.71 kW (9 hp) Chrysler engines, each driving, a two-blade propeller. Empty weight is 142 kg (314 lb).

OPEN HOUSE, please
 
We gave not had a twin tail boomer for a while. The best (and only!) picture I ever saw.

Oh brother, some help to get you started :jump:
This one-of-a-kind has nothing to do with the well-known aircraft company with the same name
 
She is American. First flight 1965. Damaged in (non-fatal) accident on 23 April 1966 when gear collapsed. Two-seater had retractable gear and I never flound out what engine was installed.
 
Hi fabulousfour:encouragement:
Maybe the Pulliam (I have this CS-1 as the Crouch & Sowers CS-1 with same N225A registration. Extenally looking like a (single-seat) Piper Cub. I understand that Charles Pulliam may have been the builder of N225A.
The twin tail boomer is the Short Model A (also seen named as One-Of-A-Kind). Registration was N238Y.

May I hand the baton to you, please
 
Thanks for the information about the Pulliam, Walter! :encouragement:

Couldn't find anything about the Short twin-boomer either :dizzy:Your database is incredible!

As you pushed the baton to me, here is a nice floater.

Hadn't thought that this would last so long. :dizzy:

First flight 1917, in the late twenties the company built aircraft in license from a well known European manufacturer of light planes.
