WW2 Air Ministry binoculars generally come marked AM and either 6E/293 or 6E/471. I had assumed that those marked 471 were a later development of those marked 293, but I have seen those marked 293 with a date of 1944 and those marked 471 with a date of 1942. Does anyone know the difference between the two?Information
