Gleaner L model year

[Anonymous-0]

Been looking at a L model combine and the owner says its on of the last model L's before the L2 and that it has alot of the updates that the earlier L's didn't have. Its serial number is LKS11749. Any help would be appreciated.

according to my my book it's a 1976 and yes the the L2 started in 1977.
