Dear Linda, I might have one of those Kilmarnock lamps, inherited in my Pollock family. It is of brass with "A. Caldow" and "Kilmarnock" on one side, and the initials of A. P. crudely stamped on the other. I hadn't realized what the double spout was for--glad to see your message and description. I guess A. Caldow was the manufacturer? I thought at first it might be the mine, but have never seen the name as a mine or owner. My relatives mined in Lennoxtown and around Coatsbridge in Scotland, then came to Tioga Co., PA, USA in 1852.
