Looking for a handful of 45 long colt brass, prefer older/vintage stuff for a display, looking for about a dozen or so. Please let me know if you have any laying around. Thanks

Also could use loaded ammo as well, just for a display, so older the better.

or any tips on where to find some. No luck on gunbroker

You can find vintage ammo at estate sales on occasion, usually when you aren’t looking for it, and sometimes at gunshots. I went to an arrow head show down in the Burnett area a few years ago and there were some there as well, don’t know caliber for sure but I think 44-40. You might also try flea markets and trade-days. I’ve got empties I can send you but they aren’t old, I could even do some dummy rounds- no powder and you can set them in the weather for a while and they will oxidize and look old in a few weeks.
