Antares 2X Barlow lens 1.25in Japan c1990

Vintage Antares 2X Barlow lens, 1-1/4 in dia from Japan, c1990. I am the original owner and I purchased it as part of a collection in the late 1980s or early 1990s, this Barlow has been carefully stored in a foam-lined case in a temperature-controlled environment (a house, not a shed or garage). When used, the Barlow was unboxed, used for observing, and then returned to its box capped. As such, it is in super condition and shows only the slightest hints of the ~35 years I have owned it.
