I'll stick with the later (1936-1963) M70s's-- way better trigger, bolt design, safety, stock dims-- That "tarted-up" M54 looks like someone tried to "put a $5K mink stole on a $5 hooker-- the Mauser wing safety makes a scope mount "iffy", and like the early M70's )1936-1942) only the front receiver ring was Drilled and tapped for a scope mount- Roger Rule covers the M54 quite well in his book "The Rifleman's Rifle", and as a rule, I refer to that book as my "Bible" when looking over pre-1964 M70's offered for sale.
