What gave it away to me is the Germans using it in some wintry-wonderland (Russia). I don't think the Germans used the 155mm on a self-propelled mount. I'll wait for confirmation.
IIRC those vehicles are French built and were used by the Germans "as is". AFAIK the 155 and 305mm versions were no longer in use in 1940 but a 280mm group existed.
according to wiki only the 194 still existed - "After the Great War all M 280 models were converted to take the 194 mm gun. Around 50 were still in use at the outbreak of World War II, some were used against the invading German forces. Surviving vehicles were pressed into Wehrmacht service as the 19.4cm Kanone 485 (f) auf Selbstfahrlafette. At least 3 of them were used by the Germans in Russia in about 1942, serving in the 84th Regiment of Heer Artillery."
Looks like Wiki is not accurate. There is a surviving 280mm at the Militärhistorisches Museum in Dresden Germany reported captured in 1940. Can anyone translate ? http://www.hartziel.de/index.htm?/_typen/chamond.htm
i believe that is a field carriage 280 - not the actual sp combination. at least one of the 280s was used at Leningrad on field carriage, and the Russians and Polish also had some. It is possible i suppose that it is actually a 194mm that has been cut and thus looks like the 280mm? Mortier de 280 modèle 1914 Schneider - Wikipedia, the free encyclopedia also found a photo of one at falaise in 44 there's a good photo of the three different barrels next to eachother;
The chassis certainly looks like a St. Chammond, having a 280mm field mount and a gunless St. Chammond chassis in in the same place looks a bit far fetched. Nice picture of the trio, I assume the other two to be the 280 and 220 but AFAIK a 305mm existed as well in prototype form but only the 194 and 280 went into production. The strange thing about all these pictures is that all are missing the generator vehicle!!. Found reference to 193e RALPA that should be one French unit that used the 194 in 1940 but none about 280M users, one source states there were 3 units altogether, also misterious is how two ended up in Italy (one of those finally ended up at Aberdeen). This shoul be the 155 so it's not in the trio And finally a pic with the second (non gun) vehicle
I think the Hartziel picture is actually showing the Schneider/Panhard chassis of the GPF and not a St Chamond, although there's little actual difference, which makes it as you say very odd they are both in the same place if they are not somehow connected. IMO that picture showing the 3 different ones also has a generator vehicle in background The variety of potential 155mm barrels available is astounding - long job to identify them all conclusively Perhaps one vehicle slipped through, or was a prototype or used for assorted trials. The 220 most likely existed at some point; http://books.google.co.uk/books?id=...&q=schneider self propelled artillery&f=false and also a 240mm; http://forum.axishistory.com/viewtopic.php?f=34&t=73088&start=120 There's almost enough variants of these to warrant a book all on their own
Since I haven't received confirmation yet, I'll post a photo (unofficially, of course): Name this one. Its post-war, but has its origins in a very familiar WWII tank.
It looks like a mixture of AFV's, The suspension looks as if its from the Sentinel from Australia but the tracks look German, The headlights,BMG and horn look British! Is it a type of heavy morter or some form of demolition vehicle?
Hi, No. Not Australian, German or British, either in whole or part, also not a heavy mortar or demolition vehicle. Also not a mixture of AFVs other than that you are very close, the suspension is of a similar type to the sentinel, and it does have a BMG, headlights and a horn
sorry, not American. European. Another little clue - it was a prototype, but the basic hull with a rotating turret instead went on to be produced in some numbers.
