Labels are excellent, though the tubes are a little dusty/dingy as I didn't want to risk ruining the labels while cleaning the glass. All four tubes have "rX3 X9E" date codes, which indicates manufacture in the Sittard, Netherlands Philips plant in May of 1959. "D" getters.
They all test between 82-84 on my Knight emission tester, where a new tube tests at 86.
Willing to split into pairs.
Make me an offer.
