I acquired this a while back and it didn't take long to see it was the same serial number as the Ruger stock photo for the TALO Turnbull Bisley Blackhawks model 0407. I believe Ruger cropped out the medallion on the grips as it appears the wood grain is the same. The box is marked RB45W which is the 7.5" engraved cylinder Bisley model but it shipped in a 5.5" plastic case after Turnbull and Ruger completed it. I just received the letter from Ruger since they have a reduced workforce due to the virus.
The first picture is the stock photo from TALO in Sept.2017.
