Super Blackhawk, S46, s/n 24489, letters with a 6 1/2-inch barrel and shipped in September 1966. I have the original box and shipper and they have been changed by using a pen to indicate a 6 1/2-inch barrel instead of the normal 7 1/2-inch barrel. Approximately 400-600 Super Blackhawks with this barrel length were made by Ruger and were most likely the result of .41 and .44 barrel stock being intermixed (per John Dougan's book on page 277).
