The Marlin records end after 1906 at around 355,300 Marlin continued with the original
set of numbers to around 450,000 but in what year I am not so sure,it is thought to be
the end of 1915 when the Marlin family sold out to investors.Either the original Marlin
Co. or the new owners started a new set of serial numbers with the pre-fix added to
the number. A,B,C and D seem to be all that have shown up.This would seem to make
one think some where around near the end of the Marlin family ownership or the start
of the Marlin Arms or Marlin-Rockwell ownership.It would be hard to guess an exact year.
