44 magnum brass question ?

I rarely reload at all but as part of a deal i acquired a ton of reloading components. First off who made browning brass ? , second is ww brass any quality is it Winchester or who made it , is RP Remington Peters and finally is there any market for once fired brass ? thanks

First, not familiar with a "Browning" headstamp myself.
2. W-W = Winchester Western
3. Yep, Remington Peters
And yes, there is a market for 1X fired brass; some calibers more than others, but .44's ought to sell
