I have a 110L 338 Winchester magnum with serial number 68463 also 12T in an oval in one spot and 38T in an oval in another spot. This would seem to indicate a 1966 model, but the bolt style and trigger assembly are both pre-1966. Father in law was original owner, and he is not around to ask any questions. Trying to find a replacement adjustable trigger. Have checked with Basix Triggers, and they have said their triggers will not work with any pre 1966 models. The trigger spring seems to be in the safety along with two other screws. The trigger does not have e clips and pins, this one has drive out pins. Any suggestions on what year this may actually be and what trigger will fit it? Thanks!
