Are these store model bats?

[grandpahoo]

I bought these bats years ago, before I knew anything about game used items. Fortunately, I didn't pay much for any of them - I just bought them because I liked them. I still don't know much about game used bats, and was wondering if you guys could tell me if I'm correct in assuming these are store models. Thanks in advance for any help you can provide.

Also, I'm a retard and have no idea how to resize these pictures.

At first glance, all appear to be gamers, but it is difficult to tell for sure without knowing the markings on the knobs. The H&B should have a model number stamped into the knob, not inch marks. The Rawlings/Adirondacks should have a model number, batch code, and year stamp.

All look to be gamers. These guys probably didn't have store bats, and each played before there were a lot of "souvenir" bats made for the collectors market.

Well that's certainly good news. I'll have to check out the knobs and see what info appears there. Thanks for the input.
