Hello,

Perhaps you would find better responses in the "Collector's Corner" but I believe I can answer your question. In 1946 and 1947 there were PX versions of the 350 series cars with Hand-Stamped numbering and lettering. However, these PX sets did not include the 352 (red), but rather the 352 J. PX sets before from 1945 had the lithographed 352 red which was actually a pre-war model but was leftover stock. So as far as I know, and there has been much debate about this, there is no 352 car in red that was hand-stamped and we are limiting this to the period from 1946 - 1947 because that is the only time range in which could have possibly been produced (and would have made sense). I believe the hand-stamped ones only existed for a few months in early 1947. Otherwise lithographed when the new 47 catalog came out.

350 series cars 1945:



Here in 1946 (or maybe early 1947, I forget...I have to check the stamps again):



and here SK 851/4 PX set from June, 1947 sold for German voltage (bought in Germany but brought to US) with lithographed cars:





Here an overview of 353 cars, the same cannot be applied for 352 but it is useful in seeing the patterns. Please note that I am missing one version of the 353 in between which I have just found (pictured above, 1946), a 353 that is a little bit more brown from 1946:



So I can conclude that there was never a 352 red hand-stamped car, at least not for sale widely or listed in any Marklin catalogs or documentation. All of this is going off of what I see "out in the wild" and not in a book or anything.

Best regards,

Paul
