A friend was cleaning out his grandfather's house and came across some old reloading equipment and components. He knows I reload and gave me a box of stuff, which included 4000 primers. Both the Winchester-Western and the Remington primers have the old wood trays. I'm guessing 50's or early 60's vintage. I'm sure they'd be fine to shoot but I think I'll hang onto them as collector items even though they're probably worth more as functioning primers in today's market.
