The Old Hippie
Interesting !AI- 1979, AII- 1977(very late), AIII- 1978, AIV- 1980, AV- 1981-82. I know of no way to confirm this 100% and I think the actual dates could vary by a few months, but when you're talking "what year" it's probably close enough.
Sako’s 1984 catalog introduces the Sako 2700 Finnsport..describing the new model as a classic European design for the American market. The line-up shows the Finnsport with the Sako Standard Sporter and a DeLux model which appears to NOT have a forward angled rosewood accent piece.
I thought for a moment that the Finnsport may be the model we find with the Herringbone checkering patterns, but the photo doesn’t show clearly enough to tell.
