Does anyone have an idea of how to estimate the date of production from the serial number? I just traded my decent, if a bit hazy, Summitar for one with very clean glass and I amazed at the difference. Stopped down, I cannot tell the difference between B&W prints from it and my collapsible Summicron 50. Mine has a serial number of 750XXX. As I have always assumed that the one million mark was hit about 1950, am I correct in assuming it is a late 1940s vintage? If so, it has certainly held up better than its owner! Steve
