It's been years since ive tripped over an interesting ruger. However, I just found a beautiful 44 flat top 6.5 inch nickel or chrome plated Blackhawk. I thought it would make a good sass gun so it came home. When I checked the SN, 20006, I found it was built in 1959.
Any ideas if the plating is ruger factory? I will get some photos midweek.
If its special, I want to know. Otherwise, I'm gonna shoot it.
The chrome plated BKH-46 6-1/2" .44 flattop that gun that was on Ruger's 1959-1963 NRA display was serial number 23481. The chrome 10" .44 that was on display was #20082. Looking at my notes, your #20006 also falls right in a block of 10" guns.
Even though your gun is apparently not one that was on display, I would still contact the factory to see if it will letter as chrome. There's nothing saying WBR didn't have more than one 6-1/2" plated. Also check the bottom of the cylinder frame ahead of the trigger guard to be sure there isn't an "S" stamped there.
And be sure to let us on RF know how it turns out!!
If it was plated from the factory, they should be able to tell you...well, they would at least tell you whether or not your gun was used for display purposes. Somewhere there would also be a record as to whether its plated or not, just depends how deep Ruger digs for the record.
