All LC Smith shotguns have a Baker patent snap on latch, which consists of a "J" shaped spring which fits against a lug on the barrel. On some guns there may be an additional latch along with the Baker latch. Guns with ejectors have an additional latch, usually a roller latch, and non-ejector guns made between 1912 and 1919 may have a Curtis latch. The Roller latch can be identified by a serrated button in an escutcheon located in the bottom center of the forearm wood, and the Curtis latch has a rod with a button on the end that protrudes from the muzzle end of the forearm wood. To remove a forearm with the roller latch, the button must be pushed forward while pulling up on the forearm. The Curtis latch is released while pushing rearward on the button while pulling up on the forearm wood. If there is no roller or Curtis latch, the forearm is removed by simply pulling up on the front of the forearm. Sometimes it takes quite a bit of effort to pull the forearm up against the pressure of the "J" spring. I hope this helps.
