Model 910018 both 73 and 74, from the serial # it is a 1974 model, last year for the 10000 series machines. Yours was manufactured roughly 400 machines after mine.
I just noticed the sticker serial # on mine is 009142 but the stamped serial # is 009141. I guess someone on the line that day got the stickers mixed up.
