This is a professional quality instrument for the serious mariner, and at a reasonable price.
Captain Joe Gomes, a merchant seaman and fisherman, owned this instrument for many years and was obviously very proud of it. It is a fine quality C. Plath sextant, the instrument that set the gold standard.
It is in excellent condition and though it is over 50 years old, shows no sign of hard use. It comes in a hard case with a working lock and key, and several small accessories. It has modern optics with a large field of view. The scope is 4 by 40.
This instrument also comes with an astigmatiser in the index shades. This is a lens that elongates the image of a star into a line. This is handy for evening observations with bright stars and an obscure horizon. Not something you may need, but nice if and when you do.
