The only information available for a telescope maker J.T Coppock is of a company in Leeds, and not London as this one. In the 1950s and 1960s, James T Coppock (Leeds) ltd was importing Antoria guitars from Japan, and indeed both Hank Marvin and Jeff Beck played one, as did Big Jim Sullivan when he was playing with Marty Wilde. James T. Coppock ceased trading in the early 1980s and Antoria guitar production ceased then, only to be resurrected later. 43 ¼ cm open and 16 cm closed and in very good order. The lenses are clear and unmarked, as is the pigskin covering. The brass has marks through use as shown in the images. This scope and maker warrant further investigation. The price includes UK delivery. OPT 853.
