I picked a used scope at LGS. Nikon . Says it's a Monarch on the side . 4-16×50. 30mm . Side focus. Says it was made in Japan. ( I thought they were made in Philippines?). Scope is all black. Like new. They charged me 300.00 incl tax and said that they were giving it away . Glass is excellent and seems well made. I can't find any information on it though. Any ideas ?
