Is there really a Marlin model 30 or is this a typo, or an urban legend? I noticed that a recent manufacture Lyman tang sight is described as fitting Marlin models 30, 336, 94, and 95. I cannot find a model 30 in my limited reference books. I have a couple of Marlin model 36's and 36 is not included in the Lyman description although the 36 is practically identical to a 336. Anyone have a model 30 that they can tell me about?
