I am trying to find out information on a gun that has been in my family for a long time. It is a Savage Arms lever action 32 cal. rifle. It has the patent date of 1893 on the barrel. Where do I find the serial number so that I can date it more accurately. Also any information I can gain would be appreciated. I am attaching one picture but can take more close-up pics if needed. Thank you for your help in advance.
