It depends what year if its from, since there have been no "real" changes to the mark 3 over the past decades the value I would estimate for your Ruger mark 3 to be worth, assuming its in new condition would be probably be a $320 value. if it is a newer "version" of the mark 3 then probably $360. that is the list price from ruger anyway. also barrel length may effect the price but not drastically and any accessories on the firearm its self. hopefully this answered your question, thank you for asking.

As firearms are usually numbered in sequence 12472 can be almost any firearm from the Brown Bess Musket to the most modern weapon. Simply put there is a 12472 in every mark of firearm manufactured in production for the last 300 years. More simply put one cannot identify a firearm from a serial number.
