WWII Aircraft Ignition Switch. Made by Jos Pollak Corp; Part #805RA. Patent numbers on housing 2,169,819 and 2,396,372. Both patents are listed in the 1946 Indexts. Face of switch has "IGNITION", with 4 levers identified as "1 OFF, R, L, BOTH"; "2 OFF, R, L, BOTH"; "3 OFF, R, L, BOTH" and "4 OFF, R, L, BOTH"; and a pull knob with "PULL OFF" on face in center of switch. I have no idea what aircraft this is for. Overall condition is very good to exellent, but it has not been tested, and is being sold as-is.
