Ford Rotunda automotive equipment catalog

Description

Ford Rotunda automotive equipment catalog. I am not sure of the year for this catalog.  My late father-in-law was a Ford mechanic/dealer and this was in his stack of manuals.  He retired in 1978 so I assume this is prior to that date.  Please look at photos to help you determine the age.  It has a "cardstock" cover it looks like different packets could be added to it as they were issued.  There is writing on the back cover.
