I have a chance to pick up a 1930's vintage Marlin 39 "S" prefix and octogon barrel. The gun is in excellant condition with perfect wood. But...it has been refinished blue. A fantastic job but no longer has the case colors on the lever and receiver. I can pick this gun up for under $600. How much did the refinish in blue hurt the value? This gun was completely restored...except the case colors. Now all blue...and a very high polish. Rich, old Colt Python looking blue, not sprayed on looking. The original peep site on top of the stock behind the trigger has been replaced with a modern reproduction. Blue Book says $1300 for a 60% gun. Is a nice restoration in blue 60% or is it less. I know the Blue Book doesn't write a check, but we all look at it for some kind of a starting point.
