The sketch matches the pinout of Texas Instruments TIL 393-9 and National Semiconductor NSA1198 displays (1st & 2nd attachments, respectively).

The 8-digit versions of those displays can be used as direct substitutes, as their pin order is exactly the same. My Sinclair PM200, for example, uses the 8-digit NSA1588A display. The apparent digit height of the NSA1588A is larger than that of the NSA1198 (please see attached data table), with the Texas Instruments displays sized in between.
