SOVTEK Katonai vacuum tube

Russian military tubes for sale as a set. (I couldn't select more than one at a time)
4 pcs 6P6c (6v6 6v6gt)
4 pcs 6p3s-e (5881)
I used them for testing and finally decided on EL34, so these tubes are now superfluous.
They all work, I don't know the exact operating hours, but they do their job without problems.
I would like to sell them as a set, but I am not opposed to selling them in pairs.
Interested in trading for guitar-related items.
