Here is a vintage arched Union No. 6 smooth bottom wood plane. Has a old 1892 Stanley blade. Do not see any cracks or repairs.  Could use a cleaning, etc. Handle has a screw that may not be original. Also some wear on the wood handle. A bit of wear to the slot were the blade goes through on the bottom. ( see second to last photo ). 18 1/8" long. A neat old piece.
