7.5cm PaK 40 is correct. RSO was a very efficient vehicle, but lack of armor did place the crew(s) at rixk of death.
Looks like it's your go, Mr. Gardner. You named it first. So what if you made a little typo. After 4688 posts you've probably got the ends worn off of your fingers. Awaiting the next challenge.
no worries here Kevin, I'm not in any contest for a record number of posts. I'm just enjoying myself, learning some unique facts about WW2 period AFV's and trying to contribute info when I can. It's amazing how many unique and innovative designs (both good and bad) have been tested in an effort to create the various types of vehicles that were needed.
Thought I would restart with a new picture; Since it has been over 96 hours since the last posting....
I have seen this in my German AFV Encyclopedia by Chamberlain & Ellis. I believe it is the chasis for one of the 6 siege mortars (54cm or 60cm) in size. To move these mortars, they had to be disassembled into transportable pieces.
Yes it is! Upper piece is chassis of Karl mortar, lower vehicle is towing trailer. And your book is excellent for german AFV.
I thought it might be interesting to show a couple more pics of the Karl-Gerat that showed it fully assembled and ready for action. This weapon was one of the largest self-propelled guns in use. Karl-Gerat when being transported by rail. Karl-Gerat 040 with 60 cm howitzer during battle in the Warsaw Uprising. It is easy to see it is using the earlier 60 cm short barrelled gun. Later versions (041) 54 cm gun which had much longer barrels were not ready for use at the time. The Munitionsschlepper can be seen loading ammo. 24 PzIV's were converted for this purpose (transporting and loading of ammunition) and 3 or 4 were assigned to each of the Karl-Gerats. Each of the Munitionsschleppers could carry four shells. Unexploded dud fired during the Warsaw Uprising. Craters left by these shells would be approximately 15 m wide by 5 m deep and could penetrate 2.5 m of concrete.
And here is one with towing vehicle attached to trailer. Note chains on back tires of truck, indicating deep snow.
It looks as though the gun has been taken off of the hull. Is that the gun being transported on back of the truck?
Maybe this might be the answer you're looking for Vathra. It is a quote of a quote of a fellow on another forum. I think you'll recognize it as you read it. "Here is quote from John Milsom's book "Russian tanks 1900-1970". Quote: T-34 light airborne tank: Between 1945. and 1950, however, a further attempt wa made at producing a light tank for use by airborne forces, which resulted in the T-34 light tank. The T-34 utilized components of the T-34 medium tank which it closely resembled (hence its designation). Other components (principally automotive) were based on T-70 / SU-76 series. The vehicle had only three road wheels per side which gave it extremely poor cross country performance, and only limited production was undertaken, no tanks being actually delivered to units. This photo is also from this book, and it is the only one I saw. On the internet there is very little data about it. On some other forum I found info that it was made by colonel Kravtsov, who was also designer of other soviet light tanks." So now we know what it is for sure, that is if the guy I quoted (Vathra), knew what he was talking about.
