Do-All "Dual" clay throwing traps that have been well used by boy scouts for a long time.
One of the traps has its ratchet stripped and does not do the 3/4 reset it is supposed to. The other one seems fine. They were broken down for transport and will both need adjustment and fine tuning to throw reliably without breaking clays. This is a very cool setup that can use the legs as shown, or can mount right in a standard 2" hitch (probably don't drive any real distance with that thing sticking out!) I could only find two of the mounting rods for the safety rings (included).
I think most Do-All traps use the same mount system, so if you've already got some you could swap them out.
Comes with three cases of clays (they don't sound broken, but were last handled by scouts) as shown.
