There were many E & G Types with the Crinkle Finish..It was just a different finish is All..They were not Types in their Own Right..The exception was the Route 66 Type G 4 but that was a Distinct Set as there were many later Type G 1s with a Wrinkle Finnish as Welli have an Injector I believe it to be an E type but the difference from the others i have and have seen, it has a stippled finish on the metal. Was this just an option or was it its own grade?? It is the second from the top in pic.
