Interesting. I wonder if anyone else has one of these.

Here is a Elgin version of the AN-5740 with ADJ to 5 position and 21 jewel when you know it's 22 jewel for the one added for the sweep hand.

Hi,Scott My 4992B Ser.no.4C554 should be 6pos.I copied Imfo. off E-Bay picture thinking it was 5pos.Everthing else is correct.Also have 4992B ser.4C531 imfo.is same except some of case numbers.Do you know how many B.U.Aero.U.S.Navy made? Hub.
