Like most models end numbers are unknown. Also there are gaps in numbering found in other models to make it seem like more were made than actually were.

1930 L-1001 to L-2700 Oct 7 1930 to Dec 31 1930
1931 L-2701 to factory closing Aug 1931
Apparently gaps in numbering from 9500 to 18500 and 18500 to 24400 in vin books.
