It's Communist China - North China Chin-Ki-Cha Border Area 1948 Young Mao. Not listed in the general catalogues, but probably in specialised China
Dave, it's not a revenue then?
No, and i just found it in my (very) old SG China, as NC60a. If imperf (I see another beghind the shown stamp), it's NC60b.
Well that explains my countless hours of searching for it. THANKS so much!!
Thanks, Dave.
And based on this info, I was able to identify it also as "Yang NC68" (I'm fairly sure). The info here made it all possible - THANKS AGAIN Kurt
