Identify that Tank/Ship/Plane/Artillery etc

[paleologos]

Sarr1n has the ground.

[Sar1n]

A partial, but should be easy...or tricky, provided you miss a couple of details.

[Spear Dog]

Consolidated B-24 XB-41 Liberator bomber escort gunship?

[Sar1n]

Yep, it's the XB-41 variant. Twin .50 in waist position and second dorsal turret are clear indications. Only one plane, converted from early B-24D, existed, and proved to be unsuccessful concept.

[Spear Dog]

sorry short delay. It was always going to be a B-24 with those stabilisers ^ .

another plane as people have probably been searching them anyway: (A hint so answer can be more specific - it's 1937)

[Sar1n]

A bit tricky, this one. It's a prototype of LWS-6 Żubr that was made with twin vertical stabilizer. The configuration proved to be inferior to single vertical stabilizer that was used on subsequent production.

[Spear Dog]

Correct. The Polish LWS-6 Zubr was a 'fall-back' design in case their "more modern" PZL.37 Los development project failed - both planes developed in tandem, the PZL was a success and used until 1944 by the Luftwaffe and Romanians - the Zubr only saw limited use (18 manufactured). The LWS-6 was based on the Douglas DC-2 - not that you can tell . Development was from 1936 to 1938 with several variants explored. The single prototype of a twin vert. stabiliser version was an attempt to address the lower than expected bomb payload when the wings were strengthened (adding weight) after a crash.

[Sar1n]

Alright. I wasn't sure if it was worth censoring the markings-the paintjob is distinctive.

[chesser2538]

Very distinctive. That there is a Curtiss Seamew, used all throughout WW2.

[Sar1n]

That is right. One of worst flying planes ever reach mass production, according to British pilots it wasn't even capable of taking off with full tank.

Your turn.

[chesser2538]

[paleologos]

Mathilda infantry tank.

[chesser2538]

Close enough. =D, your go.

[paleologos]

[AnthoniusII]

P1 Mastang early(british) version,

[paleologos]

I don't know of a P1 Mastang and for this one I am going to have to ask for the mark.

[Jagdpanzer]

Mustang Mk. III with a Malcolm Hood. This one belonged to a Polish squadron.

[paleologos]

Mustang Mk. III with a Malcolm Hood...

This is the correct answer.
Not that AnthoniusII was wrong, but for an airplane as iconic as the P51 Mustang, it would only be fair that the mark is specifically declared.
Jagdpanzer has the ground.

[AnthoniusII]

No worries. For the record.
P1 Mustang was NOT suposed to enter US service. It was a request of RAF for a high performance fighter plane that could have the advandages of both Huricane and Spitfire.
But when USAAF saw the plane's trials realised that it was better than any other design it had in orders for the near future.
P1 entered USAAF "by accident"!

[paleologos]

Why do you refer to it as P1 and not P51?
Keyboard malfunction perhaps?
