Interesting scope and an even more interesting name!
Never seen it before, but the reticle is obviously a German No.4 style, but with Japan on it, I can only assume that is was built as a factory option for somee brand of rifle, and thee advertising department bastardized " Carl Zeiss" with "Carl Worst"?
That does not mean it is a piece of crap mind you, Japan at one time was noted for manufacturing great optical products, scopes among them.
