Supports. Wikipedia's Cummins L-series article states the L10 began production in 1982 at the Jamestown Engine Plant in Jamestown, New York.[1]
Supports. A 2022 Big Bear Engine manufacturing-locations list places the Jamestown Engine Plant in Jamestown, New York, producing ISM L10, G-L10 and ISX engines.[2]
Supports. A 2024 encyclopedia entry repeats that the L10 began production in 1982 at the Jamestown plant, which is consistent with the Wikipedia entry, though it is a low-credibility source.[3]
Supports. A 2025 Truckinginfo report on the Jamestown plant says its platforms began with the L10 over the plant's 47 years of operation.[4]
Context. The present-tense reading is less certain: a Wikipedia table gives the L10's production years as 1982–1998, so the original L10 may no longer be built, though later L10-family variants are listed at Jamestown.[1][2]
