I recently acquired an Ithaca 37 that seems to be some kind of special production. I've looked on the Ithaca website, and can't find anything close to the serial number. The serial number is A17xx. The engraving on the receiver is an eagle holding a banner. Written on the banner are the words "Heritage" and "Pride". It has the old style "ringtail" foreend. Anybody out there know what it is and/or when it might have been made?
