I have a Sweden 1936 Scott Catalog number 263 re-entry / double transfer DT in the top left corner of this stamp. May be something, may be nothing - I have no idea. After no small feat I managed to rig a microscope of mine to the computer and take an image. The reason I had to do that was because my scanner would just get blurrier and blurrier the more I increased or focused on that area... and about gave up till I used the microscope. If I had a better scanner believe me I would NOT BE USING A MICROSCOPE.
Now if I can see the re-entry / double transfer under a magnifying glass - then why can't my scanner LOL !?!
Please keep replies about this stamp and this stamp only - Please stay on topic.
FOCUS ON TOP LEFT (blurry scanner image)
FOCUS ON TOP LEFT - MICROSCOPE IMAGE
If my terminology is wrong - I will edit the post.
