Just received a near-mint Schick injector, and wish to pose a few question to those better versed in the variants of these cool little razors: It's stamped "Schick Injector" with the patents 1806807 and 1969945, parallel grooves on the safety bar, molded (seamed) handle, fixed spring. Now...were all E types fitted with the caramel/amber/butterscotch (and *unseamed*) handles? Did some G types *not* have "Eversharp" stamped on the spring base? It came in the clamshell case with the 20 year guarantee on the back (dated 1940). I'm referencing Alan Appleby's Schick chart while I'm posting this, hence my inquiries. I'm assuming the Eversharp name didn't appear until 1946. I'm thinking this is an E4, but the handle & patent numbers say G type.
