Information regarding lens

Hi, I have a lens which I would like to know more about, I have tried to research it to no avail, so am unsure if it is a good one or not. The information on it is as follows: auto optomax 1:3.5 f=200mm 58 (followed by a 0 with a line through it) no 221855. On the side it says lens made in Japan, and on the cover asahi opt co. Made in Taiwan R.O.C . Any information would be helpful, thank you.

Check out this page: Optomax 200mm f3.5 (Page 1) - Manual Lens: Usage - Manual Focus Forum or this one: Lens Porn!: Optomax 200mm F/3.5 M42 (Around 5 from ebay)

The 58 with the zero with a strike mark is the filter diameter, I'm pretty sure.
