Thanks for the responses. I am specifically interested in Aaron Smith ( lived 1769-1822, with working dates about 1790 -1822). I have a few of his planes, wish I had bought more when I had a chance. His planes are interesting in the design going from decorative bevels and gouge cuts to progressively (?) less and less detail and changing from yellow birch to beech. He also had several sons who continued the planemaking trade into the mid 1800s.
He used extensive layout marks, which he did not bother to remove in the finishing stage, including scribe lines for bevels and wedge mortises; but at the same time producing a very professional looking tool.
I'm interested seeing if his planes show a graduation in wedge sizes and other details. I'll try and post some photos later.
Any input is greatly appreciated.
