Hi! A friend of mine bought a Model 28-2, with 4 inch bbl today. Serial is S304xxx. I've looked at lots of info on the internet, and in all the S&W books and searched on here. Can anyone say for sure, if this gun was made in 1967. I found an article somewhere that said S304999 was the last one made in 1967, and 1968 started with S305000. Can anyone confirm that. I know S&W did not always go in sequence, but told my friend, i would try to get him a best estimate. Thanks Mike
