Hi,
I posted your message over at RRResearch group and got this:
What is wrong with you Sumpter Valley people? I have sent the
information on your three Plymouths at least twice and nobody seems to
care. Plymouth C/N 2533 ran at one and only one location in Seattle from
1927 to 1994.
2533 02-27 4w gas 36” gauge 127 HP 20 tons Model HL4
Coleman Creosoting Co. Seattle, WA
Wycoff Wood Treating Co. “
Pacific Sound Resources “ 1992 (closed 1994)
Sumpter Valley RR Restoration Society Baker City, OR (here 07-96)
I can only assume that your archives are thrown in a box in someone's
basement and nobody bothers to check them.
John T.
