Wow, little stamp - big history. That is the beauty of the stamps.
Gentlemen, thank you very much for this information. Made me go through my Austrian stamps again

.
BTW, I have a hard time distinguishing between hand made paper stamps and machine made paper stamps (maybe this is because I do not have any machine made once

). But anyhow, my Scott catalog said that all the machine made paper stamps are Type III, which have two thinner lines around the center. Well, I looked through my stamps that I thought are on machine made paper, as well as some stamps on
ebay that are identified as machine made, and I do not see two lines anywhere.
The bottom line

, does anyone have this Type III stamp to show the lines?
