607: The AC 2-Litre is an automobile that was produced by AC of Thames Ditton in Surrey, England between 1947 and 1956. Two and, from 1952, four-door saloons were sold. In addition, as from 1949, a small number of drophead coupés and "Buckland" tourers were produced. The pic below is a 1949 example, but they remained more or less the same through '56.
5380: Mercedes 500K 1932 Convertible Replica Marlene, built by Classic Roadsters Ltd, Fargo North Dakota in 1988. The company was founded in 1979 by Gary Rutherford.

They also produced the Duke (based on an SS 100 Jaguar), Marlene (a 7/8ths scale Mercedes), Baron (a four seat version of the Marlene), Sebring (a stock appearing Austin Healy 5000; available in front engine and rear engine (VW), Sebring MX (a Healey on steroids, their high performance answer to the Cobra, and the MX, their own Cobra, with a longer wheelbase and longer passenger compartment than the typical Cobra kits.
8539: I had convinced myself this was the Cameron.

But a copy of an advertisement from 1909 suggests their model 15 runabout was a 1918 model only, or perhaps didn't reach production. So, can can I get a clue
