Fred M. Locke received a patent on this design of nested wall tubes cemented together. This was chiseled out of a powerstation attic in the Midwest this summer. 9-1/2" tall, 9-3/4" wide on the widet side, 7-1/4" wide on the narrow side, 3/16" x 1/8" chip. The p0werhouse was built in the 1912-14 era so that dates the wall tube. PayPal friends and family, check, or money order.
