We recently had the opportunity to attend a sale for the estate of Mr Keim. Among the many fine items there we walked away with a few of the wooden planes he made in his workshop. While each is clearly a fine tool suitable for smoothing wood surfaces they are also beautiful simply to admire. Sadly we got no records of the exact type of woods used and I'm by far no expert. So I'm giving my best guess at the species he used.
This plane is of a size that would generally be a jack plane. It is 15½” long with a 2⅛” blade. Its stands 6” tall at the handle.
