Tough company to find info on! It doesn't help that there is a tiny firm called Central Aviation in Wichita today (formed in 1984).
The original Central Aviation Engineering Co. does comes up in a table in
Report of War Plants and Services in Urgency Rating Bands III Thru VII, Volumes 7-10, April-July 1945, Office of the Deputy Vice Chairman for Field Production Operations, War Production Board. Products are listed a "Glider parts". So, Central may have been supplying CG-4 bits to Boeing (weirdly, acting as a Cessna subcontractor).
Another online source lists Allan B. Eacrett acting as principle for the Central Aviation Engineering Company. According to his obituary, Allan Bisbee Eacrett (1908-1988) was an aeronautical engineer who had worked for "Boeing, Hughes, North American, Northrup (
sic), and Lockheed".

As near as I can tell, Eacrett was Canadian by birth - his parents seemingly moving to the US in 1910. Prior to this, Eacrett's father lived in Exeter, Ontario. His Canadian-born mother was Elizabeth Ann Bisbee - hence the middle name.
