Absolutely phenomenal for older or newer concepts. If your main thing is refurbishing vintage clubs, this and an optional companion "Golf Club Repair in Pictures" (also by Maltby, who trained Wishon BTW) is/are unparalleled and older editions like this ISBN are all you need for a dime or two on the dollar. If you want newer material, be sure to get the latest edition. We're getting one that's older because vintage is a main focus of a fun side project (and it's financed by personal lunch money, not church or corporate expense). The book simply seems to get bigger instead of omitting older things, but if you want to work on real wooden woods while purchasing the newest edition, you may want to make sure the very latest editions still have all of the oldest material. This edition will be a bit of a sweet spot guarantee for us, as steel woods were taking over while wooden woods were still on the upswing (meaning the latter part of their journey but not virtually extinct except in novelty spheres as the 2000's and now). Ralph Maltby and Golf Works are great resources with which to familiarize oneself if one intends to get into repair or component golf assembly. He took Tom Wishon under his wing many years ago before they became competitors in component golf. Wishon components (like heads) may be discussed a bit more than Maltby (?) but Maltby's name can be seen in any PGA club facility branding the machine shop-type equipment they sell to this day. R. Maltby has a rare video or two about the physics of golf and handy tips that I would highly recommend finding, because he really cuts to the chase and is efficient, well-organized, and succinct.
