Does anyone know about a disc stamped "M-7000 Pro Disc"?
It does not any brand name on it. It is shaped like a Aviar
without a bead on the bottom edge.It must be over 20 years old. What might it be worth?

All I know is that it was sold in a package together with a special disclauncher.

I believe it to be a putter that is included with a very cheap Asian basket. Never saw any launcher.

Kjel is correct. It had a larger version of a clay bird thrower for skeet shooting. I've only seen two of them on ebay.

It does look like a blue rock thrower. Maybe THIS is the thing that instigated the "artificial devices" rule in the rulebook?!

Thanks for the link, I will pass this info along to the owner of one of these in Philly.
