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

[JRussell]

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.
