That's a model 107 and yes it preceded the model 94. 107s were made from around 1937-1953. It looks to me like maybe the triggerguard has been replaced but I could be wrong on that , I have not had a 107 in my hands in a long time. If it is in good mechanical condition , locks up tight & everything , then it should be safe to shoot. All that drop in the buttstock makes that old shotgun a kicker. I wouldn't shoot steel shot in it , the barrel steel in those old guns were not made for steel shot.
