I am trying to do some work on my dad's old Savage 24 (.22/.410) O/U and I'll be darned that I cannot find a serial number anywhere on the dang gun. I've looked it over, and over....everywhere....nothing! On the right side of the receiver it has 'Model 24' and 'Patent 2259392(or7). On the left side of the receiver is 'Savage Arms Corp'. Along with that, and worn it says, 'Chicoreb (Chicoree?....Chirokee?....dunno) Falls, Ohio USA along with an upright oval with three dash marks in it. The barrel has markings of .22 and .410 respectively. Under the barrel are the letters K M with two horizonatal arrows afterwards. Under those is the letter J. These are the only markings I can find. Thinking the serial number may have worn off, I searched with no signs of wear. If that were the case the odds are not all of the numbers would wear off anyway. Does anyone know if it was normal for an older gun not to have a serial number? This has me stumped. And the Savage Arms site has no means of contacting them. From what I know of the gun I am certain it is 50+ years old. Thanks.
