The pin info and data sheets are on Dieter's site - it's the same layout for the Sperry SP-351/352/253/354 - not complex. Yours is 4-digit, so unusual.
The Heathkit one is the SP-352 (2-digit) and was used in their clocks (GC-1005, GC-1092A, GC-2005) & transceivers (HW-104, SB-104, SB-104A). So, yours is not a Heathit one, but nice none-the-less.
