Variable Frequency Filter Mfg. by A. P. Circuit Corporation AP265-5

I am after any information pertaining to a Variable Frequency Filter Mfg. by A. P. Circuit Corporation, Model: AP265-5. A schematic and/or manual (PDF or jpg form) would be fantastic. I would also like any information possible on the company. Originally they were in NY but now that location is condominiums. I am not even sure of the year that the company went out of business since I find no record of their existence on the Internet.
 
Here is a jpg (see attached) of the variable frequency filter APC265-5 from A.P. Circuits Corp. in question. It covers Amateur Bands from 160 Meters up through 10 Meters and operates from line voltage.
