The 2 with years on them are made in the USA by buckles limited, 1986 and 1986, limited editions. I am not sure what the metal is, it feels harder than pewter. They both have little stands so you can display them when not in use. The detail level is great!
The one with 5 thunderbirds through different eras is pewter. I don't know the brand and it is marked 1976 r&s. the buckle is a little stiff and there is a small imperfection top right.
All items are as pictured.
