Thank you for your encouraging comments.
I have not yet identified a list of Serbien 1941-1945 stamps on https://www.stamp-collecting-world.com
But a good approximation is apparently provided on : https://www.lastdodo.fr/fr/areas/15...erbie?page=2
and some varieties appear on :https://worldstampsproject.org/germ...p-varieties/
would you know about alternative ressources ?https://www.stampboards.com/viewtopic.php?t=97
gives some details too showing that mint versions are cheaper than used
Is there an optimized strategy to identify stamps references from pictures ?
I have tried Scanning from Acrobat Pro ( cropping and saving as xx. Jpeg) & searching with Goole image. This has worked for Sc 2NB4
But for the attached pictures ( Waterlow printed) & with https://www.pinterest.fr/hjswalden/...tage-stamps/
, I essentially got this hit:https://www.pinterest.fr/pin/484348134906324583/

Is Jane a member of a forum known by your community ?
My initial doubts were due to UK printing for a German invaded territory , not considering properly the dates.
Should these questions be shifted to an adequate topic ?
