I have been working wood my whole life but just now, at age 50, getting getting interested in some hand tools; particularly Stanley Bailey Planes. After doing some online research and perusing online auction sites I began to wonder with all the changes over a century-- "What is the best Stanley Bailey plane type (age) for using in the shop?" Collector's value is not a factor and I realize Lie-Neilson and others makes excellent users. This is more of a personal enrichment question than for decision-making purposes. So imagine living on an island with all the various age types of Stanley Bailey Planes available. Which type would you choose if it you needed a plane as a user? For specificity let's assume it is a No.5.
