OK, I will say it again. Scott 211a described as PELURE paper is also known as THIN paper. We are in semantics purgatory at this point. Below is a link to Scott 211a's on Loral's site. Loral is the absolute largest dealer of Russian stamps and the most knowledgeable. The owner is a treasure on par with Sismondo only specific to Russia. Take a look and call him if you want to. He does not bite. This went way off of the rails for a simple thing. Pelure (Scott) = Thin. There are no mysterious twelve paper types. The print quantities are known for the paper types. These issues have been studied and cataloged to death.
