All that looks to me like HIRST ARTS work.
Actually at the bottom of the page it states: "Itar's Workshop is a licensed Hirst Arts distributor."
Of course, if you only want a couple pieces, this may be your answer.
I personally sculpted some barrels, crates, sacks, etc and made silicon moulds, so I can have any number of copies at a very affordable cost.
Anyhow, it's a good tip for cheap accesories and scenery.
