Old Brass Turning Stencil WheelI had, and quickly sold, one of these before that one with a 1871 patent mark and completely greened patina. This one does not bear a patent mark that I can see and I think may not be quite that old, but still with a lot of years on it for sure. Still totally useable for sign making or all sorts of creative endeavors, but I'd hang it on the wall by a nail otherwise, and just give it a spin now and then! 11" across including moving window; 10 1 4"
