I checked the serial numbers of the brass framed Super Blackhawks in John Dougan's book, "Ruger Pistols & Revolvers", but they were not listed. The shipping information on the FT 44 with serial number 322 will have to be obtained via a factory letter. I would also letter the two brass framed Supers as even though they are not listed in the book, it is worth looking in the factory records to determine how they were configured when shipped.
