Siemens DL3416

Here you go:

Looks like they may have the decoder built into them.
And 16-segment as mike says.


Yup, that's what they are, similar to the DL1416s used in the AIM65 and elsewhere.

A little more intelligent than just decoders & drivers; send it a 2 bit address and a 7 bit character and it'll store and display it (them) until cleared or replaced, easily cascaded for longer length.
