I been looking over this 1978 Ruger letter by Steven Vogel. ref 250 ser # guns. note it says manufacturer date and not shipping date. the dates seem odd on some of them. a few interesting guns not listed. note the single shot 456 Winchester Hawkeye magnum. im sure it was a records staffer. surely the old field and stream editor was not this bad. but he did sign it. all and all. just interesting stuff.
