The picture below shows another view of the (probably) the same ex-russian WOT-8 with BM13 Rocket Launcher, or aas you say, Stalin Organ, or as Russians use to say, Katyusha. Speaking about the WOT-8, Russian sources, as far as I know, only mentioned that "several WOT-8 were put into service", without mentioning any other details. My opinion is that all of them were used for installation of rocket launchers as there was lack of suitable chassis. By the way, the web page which Bill Murry mentioned above, with a lot of nice looking drawings of all lend-lease stuff, is not correct. All depicted vehicles were reportedly used by Russians, it is all right, but concerning the color scheme or marking, it is only the artistīs impression.
Happy searching,
Jan Mostek.
