This is a 12.5mm eyepiece in .965" size. It says "Or. 12.5mm" I think it's made in Japan, because I also have an 18mm eyepiece that's identical to this (except the size) and it's made in Japan. I don't know what brand this is. It's used, but in good condition.
$10.00 plus $2 for shipping and handling. I take PayPal!
