It's not listed in Dougans Book. The highest serial number is 140-07797, then it jumps to 140-12229, then 140-13831, and the last number is 140-24870. Serial number 140-11449 is not listed, but a call to Ruger is the only way to know for sure.
I tried to call "the nice lady" at the Ruger records department 603-865-2424. Instead of the nice lady answering you get a recording that states the records department is no longer accepting phone calls with serial number inquiries. I guess Ruger decided they can pay the nice lady's salary by forcing you to pay the $10 fee for a Ruger letter. Who is the contact person at Ruger to get this info?...You have an email address?
There are bunches of blue Old Army's that were shipped with Brass after JD's 140-07797. I think he must have stopped at a certain date in the records.
