The M-2150 is a classic power piece that was used around Kootenay, B.C. It has been suggested that they were produced in Germany and exported to Canada in the early "1900's". Generally they have been recovered with out any embossing or marking. This example has what looks like the Ohio Brass "O" with a "B" inside incuse marking and is under the outer skirt.

Here is a close up of the mark under the outer skirt.
