OK I'm new to drums (In my 60's). Recently while going through my late brother's drum odds and ends I found these. I am guessing he wanted to fix these up for his use or to sell. I dont know whats what other than I can see Rogers and Slingerland. Any guidance on what these pedals are or should be would be helpful. I'm not sure what goes with what here. I know much less about pedals and drums (though those who have seen my posts would surely doubt this). Thanks for any thoughts or instructions. And if someone has an overriding interest in something here I may be open to that to.
