Looking for information on a control box mfd. by farnsworth in 1945. control box no. is C-89/apa-5 nxsa 83373 837;cfn serial no. 837. Was last inspected on Oct. 10th 1951, by Inspecor Villandrie No. 75. Control box has a closing speed, altitude, trail, and time of fall guage. There are switches for arm and disarm release, range select, and dials for fine tuning. Any information would be helpful. I don't know what to do with it. Thank You! Mike Maki

C-89/APA-5 is part of AN/APA-5 Auxilliary Electronic Bombing Equipment and was used in the P-2 Neptune.
