Average condition cosmetically Antares (same maker as Parks and other pseudo-Masuyamas - not sure if these are 5 or 4 element) but optically perfect 15mm Plossl. VERY sharp, and well regarded along with all the other pseudo-Masuyamas. Made in Japan of course.
No heavy idiot marks on the barrel (scuff or 2). Has generic caps. No box. Notice the scuff/chip on the lip - it came to me this way (ex-outreach EP - optics are fine).
