Burroughs b50 25 tubes 6 tubes

Hi a few months ago I picked up a box of tubes at a hamfest, all of them were nl-840 but 6 of them, those are Burroughs B50 25 tubes, I need 6 in-14s, which I had ordered last fall, but have misplaced them and can’t find. So I’d like to find someone who would like to trade the Burroughs tubes for a set of 6 in-14 tubes so I can complete a clock that I am in the middle of, the tubes look to be used pulls and look to be in good shape except one of them has a crack in the top of in, will post a couple of pictures , I have not tested these tubes but I did build a 6 tube clock with the nl840s that worked great . Would rather limit this trade to someone in the USA (because of easier shipping and no customs) Message me back if you’d like to trade or have questions.

Thanks
Ray
