I and my hunting partner each bought one of these back in early 1970 since we lived some distance apart.
We would invite some friends and make a day of throwing pigeons from different angles and even set the thrower behind a building so you could not see how the bird was going to come out.
Wasn't uncommon to shoot 600 birds in a day.





I had mine mounted on a flat plate of steel so I could load it and trip it my self to shoot.

But as time went by friends passed and moved so today I shoot a sporting clays course at 3 different sports men's clubs around the area.
All practice HELPS.
