These "coffin bottom" Cutters are much scarcer than the more common ribbed bottom variant. This one's "coffin" is unusually deep--almost 1/2"--making the insulator about 3 3/8" tall. Embossing is weak, as usual.

Has some wire rub (see pic #1), and a still-attached shallow flake at one tie-wire hole (also visible in pic #1). There's a slice running up one corner, and a small chip at the other corner on that long side, otherwise base is crude but in good shape (see pic #2).

$400 plus postage from 96097. If you want more pics or description, ask and ye shall receive.
