Can anyone shed some light on this, I am looking at a Marlin L C Smith, 68 - 71, field grade, it is my understanding that all of these field grades where 28" barrels, 12 ga, with Mod and Full fixed chokes. my question is I am looking at on now that the seller claims has a 3" chamber. I cannot find any reference to these guns made by Marlin between 68 & 71 that have 3" chambers, there are also no makings on the gun that I can find to reference 3" chambers. Did some of these guns come with 3" chambers?? If in fact this gun does have 3" chambers would it be an after market modification??
