Recently, I've picked up two old imperforate similar stamps in box lots that I have no idea as to date of issue or identification. If anyone knows the country and Scott Catalogue number, please enlighten me. Thanks!
That stamp is pictured in the illustrated stamp identifier in the back of every Scott catalog. Don't forget to learn to use the catalog as a tool. Like a hammer, once you learn how to use it, you'll be able to nail it.
