I am not an expert on Oldsmobile but this clock dropped into my lap so here it is.
Listed here is an electric 1954 Oldsmobile Clock NOS
This clock is an original GM electric clock. It is in mint NOS condition for its age. Because it is a electric clock, you will find included the original GM instruction sheet. The GM part number for this unit is 983099.
The chrome is nice, the glass and lettering is clean and not cracked or crazed. The knob is in excellent condition. I do believe you will be happy with clock.
