Comments:

I purchased this machine in December '23 from a longtime friend. He acquired it many years earlier and used it sporadically, so apparently it does work. Rumor has it that this machine was originally owned by the Baltimore Gas & Electric Company (BGE), but that has not been confirmed. I have not yet reached out to Straitoplane for the birth certificate, but I'll update when/if it yields any relevant information. This old mule has been ridden VERY hard: there are many repairs to broken castings, at least one of which has failed and will require repair.

Comments: The second oldest Carey Machinery nameplate I've seen. I love how whoever drilled that hole indexed it on the "O" in Baltimore.
