I've had about 10 early model Masports from 1969 to 1977 ,Vulcan ,President ,Whirlwind and have had the later Jaguar ,I've never seen a early one with the Jaguar sticker on the cowl but have had about a mid seventies Masport that had just Whirlwind on the front of the cowl the sticker was the same as the red sticker below but the sticker was blue .
On the back top ledge of the base there is a chassis number the first two numbers are the year of manufacture ,you could look for that Seanoss to see what year the mower is.
