Final Help With These Stamps

These stamps will be the last that I ask for as I've done sorting out everything that needs to be sorted and just on to finish my cataloging my African and Middle Eastern/Central Asian collection which I was supposed to do a month or so back. Also as some requested I will make a separate thread with ALL my stamps that you guy and gals have helped me identify as a sort of catalog for this forum, including the year, catalog number and country. I hope you guys/gals enjoy that resource! In any case, here are the last 3.

1) This is somewhere from south east Asia. Siam? Thailand?



2)You got me as where this is from. I want to say somewhere Russian related right?



3) Can I classify this as Belgium and is it a stamp?



Thanks a bunch guys!
