Welcome to TFF xxkillerfearxx!!
The 49 never came out with a "Chrome" Receiver.It sounds like it was painted or it is the bare alum.I need to see pictures to tell.
The 49 does not have any real value except for people that want it
Is it a common 49? If it is not the single shot then it is the 49r that is worth a little more then comes the Presentation, and the ST. Louis Bicentennial they are worth the most.
But if it is a single shot at 100% it is worth $145+-
49r-100% is $265 down to $160 at 60%
Put up some pictures so I can tell you about the receiver.
As for rebluing the barrel if it is NOT original now then doing this will help it's value(depending on how bad it is.)And I am talking HOT blue not cold blue(cold blue sucks).
The receiver is aluminum so this was painted gloss black.
Does it have a gold trigger or hammer?
