What I am saying is that Ruger goes by the mistake , apparently, and will not deviate from it. Whether the flood occurred before the production of the OMBH brass frames or not , Ruger uses that as an excuse for a lack of records or the inability to produce them. I have spoken at length with Ruger and get nowhere. Not trying to start a fight , I was just curious about the OM in question . The serial of the OM that lettered as a 45/8" and not a 71/2" which it is, is 45-192XX which falls within the parameters of Dugans book on brass frames.
The flood loss simply referenced that if the piece had been sent in for a barrel change, there is no record, ie, work order. Probably will never get accurate records on the 45/8" vs 71/2". Hoping someone had a similar experience as mine.
