I had a 788 in .308. they debuted in 1967 in four cals: .222 rem, .22-250, .30-30 and .44 magnum.. $84.95 US dollars. The .308 was introduced in 1969 ( summer of love, first grade for me ) 1969 was also the first year left handed 788`s ( in 6mm and .308 only ) Oddly, the lefty 788`s ejected to the right still. The 788 was discontinued in 1983, and stocks were fully depleted by 1985. None of this answers you question, but I miss my 788 and felt like a trip down memory lane. Yours would probably a good bit more than 20 years of age, but if it was anything like mine, it will still be serving you well in another 20. Also, no pig I ever shot with my 788 in .308 ever got up again.
