Help to establish the exact catalogue configuration and provenance IWC Cal.83 1941

I have an IWC Cal. 83, movement 1.055.149, case 1.097.473, apparently from 1941, with a 34–35 mm Staybrite case and a rare Roman numeral dial. I am trying to establish the exact catalogue configuration and provenance before considering a sale.

Thanks
