hey guys, I searched google for about an hour. I need the date of manufacture on an Ithaca Model 37 Featherlight 12 gauge I recently got. It was my grandfathers and now I am the owner. I would like to know the date of build if possible. The serial is 6806xx. I'm going to shoot it this week sometime hopefully. The gun is in amazing shape. I'll post pics tomorrow. Anyway, any help would be appreciated.
