This auction is for an antique Abbott automatic check perforator. It has an 1891 patent date and marked as shown. Measures approx. 6 3/4" by 7" at the base and weighs 9 pounds. It stamps and rotates just as it should but there is some paper stuck in it that needs cleaned out. I've made no attempt to clean but it should polish up nicely. The photos show it well. I will be happy to combine multiple purchases to save on shipping.
