Gruen Curvex Trooper cal 440

Thanks for the info Mike! Wadsworth date, would that be the first # in the serial #?

This appears to be your classic Curvex Trooper. Style Number of 450 and the Wadsworth case date of 1944 is close enough to help support this ID. But it's mostly the watch itself and the 440-450 that makes me think that's it.
