I found this at Active Surplus today for $1.50. It has eleven LA-301VL (7-segment common cathode displays) on a 2-layer pcb.
Numbering the pins and digits from left to right, here's how the pins correspond to digits:
Digit
1
2
3
4

7
8

10
11
Pin

18
With respect to the segments, here's the relationship between the segments and the pins on the PCB:
I'll need to build a multiplexer to control the display. This should be interesting.
