RCAF Waltham

I got this a few weeks ago. This Waltham was issued to the RCAF in 1942 and had a long service life into the 1960's during the 1960's they did the dial change with the white dial with RCAF on the dial. Was missing the dust cover I had a Elgin one in my parts box it fit. Has a Waltham A-17 crown that the RCAF might have used when they service it. But I got a correct crown will have my watchmaker replace it.
