Hello, Aufklarung!

Exactly, this is Soviet experimental medium anti-tank (not assault if to be 100% correct!) SPG SU-101, which was built by "Uralmash" (Ural Engineering Plant) in spring 1945.

That SPG (SU-101 or "Uralmash-1") had a new progressive design, which made possible to install more powerful guns than of serial SU-100 and more strong armor. SU-101 was armed with 100 mm gun D-10S and the similar SU-102 was armed with 122mm gun D-25S. Both were based on the chassis of the new medium tank T-44.

The photo I've posted shows SU-101 during ground tests in summer 1945 - http://www.weapon.df.ru/tanks/sovsau/me ... lmash1.jpg
The Aufklarung's modern photo is from the Russian Kubinka Tank Museum (Moscow Region) - http://www.tankmuseum.ru/images/p2/su-101.jpg
On the same site I found a very interesting photo - http://www.tankmuseum.ru/images/pav1-4.jpg (Soviet super-heavy SPG with double treads and round hull!, 1957)
http://www.nemo.nu/ibisportal/5pansar/5 ... oyanov.jpg

(more than 60 t, 266-305 mm armor, 130mm gun, 1000 hp engine)

Specifications of SU-101: weight 34.1 t, crew 4 men, armor 40-122 mm, armament - 100 mm gun D-10S (35 shells) + 1x7.62mm DT + 12.7mm DShK, engine V-2-34 500 hp diesel, speed 54 km/h, range 350 km.

SU-101 was very powerful AT SPG, it had excellent maneuvrability and strong armor (better than of much more heavy IS and ISU), but it was not very convenient for the crew because of the relatively small fighting compartment. Serial production of SU-101 was rejected because of the end of WWII, also Soviet Army had already a lot of serial SU-100s and the serial production of new main battle tank T-54 with 100mm gun should be started soon.

Please, your turn!

Hi BIGPanzer

Thanks for the information; good pictures too, especially the first on.

Hi

Yes, BIGPanzer, that was a good question.

I looked for some time thinking it was an 85mm gun or SU-85 variant.

How about this:

Cranston & Johnson [#1] M1941 (with the bipod. M1944 had a monopod and a different butt)

[#1] According to David Miller, The Illustrated Directory of 20th Century Guns. However, Hogg calls it just "Johnson". Cranston Arms Company, RI, was the manufacturer while USMC Captain Melvin Johnson was the designer.

Yow! That thing looks like a flyng saucer with a hard-on. I don't think I'd want to be around when it showed up on the battlefield.

IIRC that vehicle (Object 279 Troyanov ) was designed to withstand the shock wave of a nearby nuclear explosion without capsizing. Hence its particular profile.

Next question, airplanes and their engines.

In the picture (censored to hid the testbed plane) we can see one of the exceeding few radial engines with THREE rows of cylinders.
This is also one of the exceeding few water-cooled radial engines.
This twice unordinary engine flew briefly during WW2, but then the research work was stopped.

Name the engine (and the testbed plane).

Folks, it seems I hit on something difficult.

Hint #1 (after 24h): engine and plane came from the same industrial complex (although the two factories had slightly different names).

Plane: Armstrong Whitworth AW.38 Whitley II (K7243) ?
Engine: Armstrong Siddeley Deerhound Mk.III ?

Correct. To you.

Thanks.

The engine was easier than the plane.
New one, name the car (sorry for the poor pic)

Thank you (that's where I found your photo too - just confirmed my answer though).

And another amoured car for you....
