Piece on the left is a Boch Patent U-928. Most likely found in Colorado as that's where a lot of them were used. This one is in very nice shape. Chris Hedges told me that you never see mint ones and this one is no exception. It has a faint and tight hairline at the base and an inside of outermost skirt flake/chip. You can barely see it from the outside. Displays mint! Incuse embossing is nice too. Says BOCH PATENT

Last line is a little faint on the bottom of the letters

The M-2150 Kootenay on the right is unmarked and in mint condition with some as found dirt inside the pinhole and skirt

(Copied from Bob Berry's post) "This M-2150 was used around Kootenay, B.C. and was likely imported from Germany in the early 1900's. This example is unmarked.

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

The aerial fuse strain in the middle was most likely used in France as they have identical pieces in glass. It is marked RICHARD GINORI in the wire groove and could use a bath too.

Prices in the pictures.

Shipping additional and should be in $15-20 depending upon which flat rate box they will fit in.
