This M-2150 was used around Kootenay, B.C. and was likely imported from Germany in the early 1900's. These are typically unmarked, but this one has a B inside a circle (not Ohio Brass) incuse marked under the outer skirt. This scarce multi-part is VNM with just a small bruise on the inner skirt. $65 plus actual postage.

Note that this has eaves to guide the rain from splashing on the cross-arm similar to the Niagara U-937!
