Vintage 1936 RICHFIELD Service Sales Manual, Exceptionally Rare Find

Description

1936, very very rare bound 9.5" X 12.1" dark blue sales manual for service station use.  Many chapters tell affiliated stations how to do things the Richfield way.  This is back in history - when gas stations were also, "service stations" - and self service was not a "thing".
As shown, great vintage condition save for a few pages (shown) where the print overlapped - must not have been caught or deemed important enough to replace, or perhaps this is a rare survival of a manual that should have been replaced!  Either way, here it is!
Last 25 pages or so are advertising from places like Arvin Radio, and other Richfield approved accessories (Champion plugs, etc).  Rare to find and great for the collector.
