Hello all...I'm not so new here but cannot seem to find my old acct info...anyway, I recently acquired a 110L in 308Win that is perplexing me...I am aware the 110L was made between ~1959 and 1962....this rifle is a Chicopee Falls, Mass marked receiver an the barrel code is K (1959) but the SN is 227XX...the SN seems too high for what would appear to otherwise be a 1959 gun...thoughts?
