I picked this little (N scale) item up on eBay for about $11, but have been unable to identify what it is. It looks very similar to an RS-11, but it's got six axles instead of the RS's four. I've run every kind of search I can think of and some came close but still no cigar. Does anybody have any ideas? Remember some time ago I started a thread confessing to be an engine illiterate? Well, I'm better now but this one has me stumped. ps:I don't even know who made it. The only marking is on the bottom of the trucks and says Yugoslavia.
