Serbia Type Os4 With Overprint

I found overprints for these in Serbia 2NB32-35 but they are the wrong values and types. Any help identifying greatly appreciated.

How wrong values? YU 159C-E, Yvert 401-403.

They are Yugoslavian, Scott#159A-159E for the whole set.

I could identify the stamps right away, but the question made me look at them afresh and ask additional questions.

The overprints are not of stamps issued by the Kingdom of Serbia but rather German occupation stamps issued during World War II.

The overprinted stamps, which show a crest that is identified with stamps of communist Yugoslavia (see Scott J38-50), were issued in December 1944. I think the overprinted words say Democratic Federation of Yugoslavia. These are the first issues of what Scott describes as the "Federal Republic."

The last issue of the Kingdom of Yugoslavia before the German occupation was in September 1940.

So I presume there were no supplies of old Yugoslavia stamps to overprint, and when the country was liberated they were forced to use German occupation stamps. But that's just a guess. Maybe someone here knows the story.

I think you are about right. Although the availability of old Yugoslavia stamps may be speculative. It may have been convenience with German stamps being at hand.

"They are Yugoslavian, Scott#159A-159E for the whole set."
Correct you are. I looked for 20 minutes and did not find them. Thanks - need to have more coffee before starting with the stamps.

I've had times when the stamp was on the first page I looked, but for whatever reason it would take me a couple of minutes looking at other pages before returning to where I started!!
Modern catalogues make it easier then the catalogues of the '70's, though.

We've all done that sometimes I'm sure. I had a real brain fail yesterday where I couldn't find Annam & Tonkin in my Scott catalogue. Was looking before, not after, the Andorra section. Time for some remedial ABCs apparently...
