Offered in 1931 and 1932 at $22.50 per club, Master 30 woods found few buyers as the Great Depression in the US was well under way.  MacGregor was hoping the sheer beauty of the clubs would entice golfers to part with the dollars.  

The construction of these clubs—a driver, brassie, and spoon, is unique. A persimmon wood head is encased in black Mac-Oid. (Mac-Oid is a variation of Pyroxylin and was applied by a patented process.)  The white face and the red Scruloc inserts are all made from Mac-Oid as well.  The large white back weights in this set appear to be ivory, complete with the grain normally found in a sizable piece of ivory. A beautiful strip of mother-of-pear is inlaid across the crown of each club.  The Bristol Gold Label shafts in these clubs are also covered in black Mac-Oid.

The driver has black face dots, the brassie has green face dots, the spoon has red face dots.  The whipping at the base of each grip and the dots on the butt of each shaft is also color coded to ID each respective club.

The clubs are attractive in their appearance, and are solid.  There are a few extra scoring lines cut into the face of each club, but the extra scoring blends in.  The face of the driver appears to have been lightly sanded once upon a time, so the scoring is weak in spots.

The original black color on all three woods has faded a little, to a blackish gray.  Such minor fading is normally found on about every Master 30 wood that your might come across. The clubs, however, still look quite natural and attractive, as you can see in the images.  The original leather wrap grips show little wear.

The Brassie and Spoon shaft bears its original "Mac-Oid" stamp.

These three woods present well and are in better overall condition that most Master 30 clubs that remain.
