Came across this one in my collection.
According to both Scott and SG this was issued only in Black.
I compared the design to genuine stamps online and it looks pretty good except that the plate looks very worn. However, the paper does not look right. It looks as much poorer quality than the paper for other stamps of this period. Also, it does not look like an engraved stamp (no impressions on the foil too).
Wrong color, worn plate, wrong paper, wrong printing.... if it walks like a duck it is a duck, right?
In this condition it not worth really anything even if genuine, just curious to see what it is.
