The patent changed for the 1914 batch. Rounded rear sight and narrow blade front. Further info can be found on coolgunsite com, or the Clawson book.
I was limited to only 12 photos and strive to show all the features, including the remarkable blueing & various grinds, polishes and most importantly the markings, which show no tell tale rounding from refinishing. All photos taken with an iPhone 7 without filter or enhancement. Thank you for viewing this exceedingly desirable colt slide.
