I used to teach Mo-Skeet for a scout camp, back in the 50's (along with riflery and archery). It was a great way to get youngsters interested in moving targets.
The target-thrower was made, I believe, by Mossberg. It did not attach to the gun barrel; rather it was a small version of your standard back-yard target thrower. I still have a couple of dozen of those targets; they are sort of like sporting clays "minis."
We used Remington single shots (Model 513?)with the Routledge bore, and so marked on the barrel. I have a Remington pump smoothbore, about 25 years old, which does not however have that bore.
