I realize its a Teacher made by Perceptor. And I've read about Dave Pelz. I guess i was a little vauge in my question... There isnt much information on wiki and google about "the teacher" line (that i can find). I've found a few images of the putter but none that look quite like mine. I guess my real question is: is this a good putter, is it valuable/rare or just a paper weight? Display case, golf course, or dumpster?

Please healp me identify this putter. Got it at a garage sale with a whole set of clubs. Says "perceptor golf LTD" "the teachers mark" Seems pretty old and i cant find any info online about it. Thank you.
