Here is my first attempt at decoding Sako factory records based on the scanned page posted by Rogan. I expected comments (“Huomautuksia”) column to include a lot of the same information that can be found on the product sticker found on the end of Sako factory boxes. For this reason I looked at several photos of these stickers & unmodified rifles from 1960s and 1970s that these stickers came with for clues what the abbreviations in Sako factory records could mean. Other sources used included old parts diagrams for L579 & L61R rifles and Urheilu & Kalastus Oy’s 1965 price list for Sako rifles. Two formats have been used for decoding: Finnish abbreviation → meaning in Finnish = English translation (additional info in parentheses) Finnish abbreviation / word → English translation Abbreviations related to rear and front sights: at. → avotähtäin = Open sight (Tangent sight, Part No. 3-11) dt. → reikätähtäin (diopteri) = Peep Sight (Part No. 961-21) lt. → laippatähtäin = Flap sight (Two-leaf express sight, one standing and one folding) id. → ilman diopteria = Without Peep Sight (front sight only) it. → ilman tähtäimiä = Without sights (no front or rear sight) m/Williams → Williams rear sight (found on 1974 L61R comments) Kiikarikiila → Scope base (Literal translation “scope wedge”, found on VL-63 comments) dpt. →diopteritähtäin = Peep Sight [likely meaning] Hop. jyv.→ Hopeajyvä = Silver bead (front sight with silver inlay) helmij. → Helmijyvä = Pearl bead Abbreviations related to stocks: Matta → Matte lacquer finish Mannl. 20” → Mannlicher stock, 20” barrel Mannl. 24” → Mannlicher stock, 24” barrel Kumip. → Kumiperälaatta = Rubber recoil pad (Part No. 552-128) Miscellaneous abbreviations and information: Lukonkehys romu → Scrapped receiver Lukkol. →Lukkolaite = Action Uusi malli → New Model R → Raskas = Heavy (indicates heavy barrel) [best guess] D → Deluxe [best guess] UL → Uusi lukko = New Bolt (found on 1968 L61Rs) [Best guess] A-koht. → Asekohtainen / asiakaskohtainen = weapon specific OR customer specific [best guess] Abbreviations with currently unknown meanings: pt. → ? op. → ? pp. → ? m/9, m/10, m/11, m/20 → ? (related to 1959-1960 L469s,) m/14 → ? (related to 1970 L461s) m/28 →? (related to 1959-1960 L579s) m/40 → ? (related to 1968-1970 L61R Magnums) Version History 8/6/2020 First version 8/10/2020 Added translations from scans sent by stonecreek, minor edits to previous version 8/12/2020 Added one translation & one clarification Disclaimer: I feel quite confident about the decoding [unless otherwise noted], however the only people who know with absolute certainty what all of these markings mean, are those who wrote them into the ledger back in the day.
