can't tell from that pic if it's 6 or 12, the foot start was used with either, but if it still has the ID tag, 6V will be black, 12V red - there were 6V starters in cars that used the solenoid key start setup .... powerglides had "flywheels"? the higher tooth count flywheel is post-55, and if your 235 is newer than that maybe it has the flywheel needed for a 12V starter, which may be why the starter was left out
a 6V starter will work fine on 12V indefinitely, as long as you don't grind away with it for extended periods, you need to keep the engine well tuned so it starts quickly, lots of folks here have kept the 6V starter when converting to 12V
