First of all thank for all your inputs! Khj, I`ve checked the area under magnifying glass, no sign of damage. Regarding the perfin, I guess this should be A A / B (but I still have no idea for what it stands for??)
, and as it is diagonal I guess first A belongs to the other perforation.
After considering all these, in 2 days I`ll list this stamp on
ebay, as it is, trying to describe all possible faults.
Date of postmark 31 De 95 (?).
ps.- I had to resolve some things, before I reply (made a donation to the site, before let you know I will list it on
ebay - and now my conscience is clear(er) ;)
Thanks again!
