Yesterday morning I stopped in my local store as part of my morning ritual and in the case a New Model Blackhawk .45 caught my eye. The 7 1/2" barrel markings looked like my Old Models. Upon closer examination I noticed that it also had Old Model grip medallions. Luckily it came with the original red box and to my surprise the box contained a matching 45acp cylinder in its own box and red bag. Even though the end of the red box didn't say convertible.....it obviously shipped that way. The inside lid of the box says January 1973.....The serial number is 46-056xx. It is in absolutely mint condition and I snatched it up immediately. My question is......should I write in and get a letter from Ruger to nail down the manufactured date? Have the early New Models attained collector status yet? Thanks!
