Just acquired a bunch of these lamps. They're in the same mini-bayonet
style as lamps like the #44/47. But would anyone know if these lamps can
be connected directly to 120 volts? Or do they need a resistor, @ if so,
what value?

That lamp is set to operate at 120V AC, so no, you don't need a
resistor. I do think they may be putting one in the base.

A NE-2 however, does need a resistor.



While some neon bulbs with a base may not need an external resistor, this
one needs an external resistor.

All the data sheets I looked at states they need an external resistor ,
usually a 220 K .
