Here’s a former US Army Air Corp narrow-gauge Plymouth....now Newfoundland Hardwoods #31 at Clarenville, NL. From info I could find it was originally #7596…built in 1942 and used at the United States Naval Air Station in Argentia, Newfoundland. Also at Clarenville is #32, I couldn’t find any info but appears to be of similar lineage.....and CNR #900, a GMD NF110 narrow-gauge unit.
