These are easy to have made. I get unsolicited advertising sent to the website email-box from a company in Pakistan that does only this type of high-end embroidery for military type insignia and decorations. The tone of the message was suggestive that if I can give them something to copy, they can do just about anything. I guess I would be wary of anything like the above. Unless you can establish provenance.
I would buy such items only from the original owner (ie, the veteran himself). There are more fakes than originals in the market. I know people who make them in Moscow and St. Petersburg.
One of my customers had just pointed me to a large website specializing in high-ranking late Soviet uniforms. they have an incredible selection, but all items are fakes. I think I will never buy another mint condition uniform again. :(
