Works numbers were 29668 in December 1906, 32221, 32286 in November 1907; 33356-33358 in April 1909.
A quint-partite assembly of logging roads in Louisiana all owned by the R A Long interests. Although none of the 5 short logging roads connected to each other, they all struck points on the Lake Charles & Northern Railway.
The L & P operated several of Baldwin's standard logging Prairies. Hudson River Lumber Company was credited as the buyer for the 20 and Calcasieu Long Leaf Lumber Company for the 70-71. Both of the latter later operated under the Longville Lumber name. Three additional locomotives were bought directly by the Long Bell Lumber Company.
46 later was sold to the King Ryder Lumber Company.

The Baldwin spec says Longville Lumber ordered these relatively powerful logging Prairies. It's not clear from the record when the 99 was sold by sister company Long Bell Lumber, but it may have occurred when the L & P was closed. The engine wound up working for the Angelina County Lumber Company of Keltys, Texas.
47 was later renumbered for Long Bell Lumber as their 11.
The 69 originally operated on the branch serving the Calcasieu Long Leaf mills at Lake Charles, La. It then served several masters beginning with Rapides Gravel Co in Woodworth, La, then Mid State Materials Co. MSMC sold the engine to dealer George Silcott in 1968, who sold it in 1970. The locomotive then went international to end up in the hands of William Richmond of Strome, Alberta, Canada. It was last known to be in storage by Ronald Bergseth of Sedgewick, Alberta.
