The Model 88 Carbine intro'ed in 1968 and discontinued as the entire Model in '73. The Carbine featured a plain, as in 'unadorned' stock, which by then, ultimately better than the 'new & improved' "impress checkering", oh my!
A unique styled barrel band held in place by a sling swivel fastener piercing the band into the stock. My singular complaint and that 'picky', is that the factory swivel, looking "tacked on". The barrel length was 19". Essentially unless an 'intruder' with all those attributes, likely just a cut down barrel without 'further intent'. Mine, pix below, by serial number on cusp of intro 1968 and yet not with the new GCA '68 mandated serial range Alfa-prefix designator.
Best & Happy Holidays!
