I figured I’d throw something new into the mix. 
yeah,. should have some variations 
and its DANA 152 SPG 
Close enough gumalangi ! its the T-4E1 Geez, I figured it was weird enough to take a day or so to pin down. Good work!
the christie suspension is unmistakeable,. the search starts from there 
i was confuse of the two,. but the E1 looks got rotating or semi-rotating turret
as this should be a medium level quiz,. anyone could solve this?

the file name give a clue 
The T-4 Tank has the turret, the E1, and E2 vehicles seem to just have a superstructure, but honestly, I cant tell the difference just by looking at the images in your link. I chose the E1 because I found it in a book, and googled it to get an image I could upload, and the image was labeled E 1. I was hoping the roadwheels would be confusing in that the British used a similar type on some of their tanks, and it had the Christie inspired look of a Soviet design. You folks are just too sharp…
I think I’ll be needing a better book… 
Polish PZInz160 tank destroyer, I think. This is probably a prototype or mockup since, as far as I know, this type never entered production. It was in fact the failed competitor with the TKS-D tank destroyer type, using the same armament - 37mm Bofors antitank gun (main) with two 7.92mm machine-guns (one forward mounted, one top mounted for antiaircraft use, as seen here). Surviving records on the development of both the PZInz160 and the TKS-D are somewhat patchy; it is not clear why the latter was preferred to the former, as their performance, overall, seems to have been similar (although there were noticeable differences of detail in matters such as track length, ground pressure and fuel consumption). In any event, production of this machine’s successful rival was small. While hampered by their very light armor, either of these vehicles, appropriately used, would have been useful little tank destroyers at the start of the war, thanks to their Polish/Bofors 37mm gun. Best regards, JR (emmm … I have seen this photo before, recently; can’t remember where … JR).
Also, a good chunk of those designs also made it onto this board. I remember I posted the M4 Combat Car a while ago and it was guessed right away.
Oh, and let’s not forget that if any of you are players of a little game called World of Tanks, the M7 Combat Car was a Christmas gift last year and quite a lot of them can still be seen ingame.
I, for one, got rid of mine, because I wasn’t very happy with the feeble punch packed by the .50 cal machinegun when compared to… pretty much everything else, really. I’m also more into long range gunnery from a concealed position, so it definitely didn’t fit my playing style.
Of course you saw it, I posted it a month and a half ago, and it was you who guessed it. XD.
It’s on Page 92.
Also, sorry for my lack of activity - I came back from my vacation and I have a lot of projects to finish.
:oops: Sorry, Wingsofwrath - seem to have had something of a “senior’s moment” here. Hope you had a nice break. Best regards, JR.
ah,. sorry,. its a repost question after all,. lol,.
have it a go sir 
Thanks, gumalangi. What about this ? Best regards, JR.

Spain,. during civil war,. where tanks and armoured cars were made to available resources. 
Spanish civil war,. CONSTRUCTORA FIELD Nº2 or Blindado Field Nº2
whichever it was,. but similar picture there is
i know i am right,. sorry for Mr JR for bypassing your confirmation on your post,. so i go ahead with my mysterious pic 
whasis?

no clue will be given,. as this should be veeery easy 
Looks like a KV1, has turret of KV1, KV1 is too easy…
KV220?
negative 
KV-1 model of 1941?
fraid not sir 
Well… How about the Panzerkampfwagen KV-IA 753(r)?
Actually, I have a gut feeling that thing is in fact a T-150 or Object 150, a 1941 prototype up-armoured KV-1 (90mm of armour instead of 75).
It was heavier than the standard KV-1, but mounted the same F-32 76mm main gun as it’s predecessor. Apparently the prototype saw action at the siege of Leningrad.
Oh yeah, I forgot about the T-150…
