Hej Ed,

Your stamp is perforated KI, 2nd row, which reduces the possible positions to a minimum.

It should be print 2, pos. 32. A constant frame-flaw seems to be the grey dot between ball and ornament in NNW.

For comparison see scan, which shows this position from both sheets at the Post & Tele Museum Danmark. But I do not dare to decide if this is really OF.80.

Mange hilsener! Bernd
