Armand P. Bayardi is a US company, makers of terrain items for dioramas.
From another post: "The quality of his work is unsurpassed, as far as I have seen. He was a jeweler in the past, and it shows in the detail he puts into his work. In addition, he is one of the best resin casters working anywhere today."
I can concur.
There is no mailing address or website shown on the product tag. Can't find a Bayardi website either, but there are many links to US retailers who stock it. Don't know about UK/Europe stockists.
Not much help. Sorry.
