Offered here is a beautiful John Gourlay feather ball that shows little to no use.  The Rev. John Kerr, among the greatest historians known to the game, wrote that John Gourlay was the best there was at his craft:  "As a feather ball maker Gourlay was unrivalled." (The Golf Book of East Lothian, published in 1896. see attached page images.)  The February 2, 1898 issue of The Golfer magazine also speaks glowingly of John Gourlay, printing that he made feather balls "as no other man could make them." (p. 86)

This beautiful example is stamped "J Gourlay" on the cover, the stamp is faint but it is all there as shown in the images.  The seams are all tight as are the two closing stitches. And the ball is amazingly rock hard yet resiliant. Indeed, this ball is beautifully made.

Feather balls—made with a leather exterior and a feather-filled interior—are the oldest remaining golf balls known.  According to Thomas Peter's 1890 account in Reminiscenses of Golf and Golfers (p 8-9) the making of a feather ball was almost a science:

"The leather was of untanned bull's hide, Two round pieces for the ends, and a strip for the middle were cut to suit the weight wanted.  These were properly shaped, after being sufficiently softened, and firmly sewed together—a small hole being of course left, through which the feathers might be afterwards inserted. But before stuffing, it was through this little hole that the leather itself had to be turned outside in, so that the seams should be inside—an operation not without difficulty.  The skin was then placed in a cup-shaped stand (the worker having the feathers in an apron in front of him), and the actual stuffing done with a crutch-handled steel rod, which the maker placed under his arm. And very hard work, I may add, it was.  Thereafter the aperture was closed, and firmly sewed up: and this outside seam was the only one visible."

By all accounts, the making of feather balls was hard work. A good feather ball maker working by himself crafted between 3-4 a day.  It was also dangerously unhealthy work.  These artisans were prone to contracting lung trouble and asthma from working in such close proximity to ordinary cocks and hens feathers, which is what Tom Morris identified the feathers as when asked about it in 1900.  (Golf Illustrated, 7 Dec. 1900: 204). 

John Gourlay was married briefly to Jessie Robertson whose death at age 24 was reported in the 16 May 1845 issue of the Glasgow Harold.
