While McDaid was working as a clubmaker in the 1890s, he changed his focus to the world of golf balls.  In 1904 McDaid applied for a patent on a golf ball core winding machine.  McDaid is listed as a golf ball maker with premises on Easter Road in the Leith Post Office Directory for 1909-10 (with his home at 14 Restalrig Terrace). The next year the entry is for Martin McDaid and Son, 326b Leith Walk.

This embosser was used by Martin McDaid and Son, Golf Ball Makers in Leith, and is in fine working order.  Push down on the handle to emboss a piece of paper set in place under the steel die.  The embossed mark of McDaid and Sons is in the images. A Very heavy piece in original condition.
