I just bought a pair of these that test like new with equal triode sections. i have seen the bugle boy, treble cleft and PQ logos on the 1950's Amperex long plates. but never the script logo. i would venture to guess that these are very rare. are any of the folks here familiar with these?

Never seen them before. Either fake or a special tube. Got me.
