Dlang 94 is correct , fenders , creeper , and headlights were all options as is a rear lift . All options are somewhat rare and most originals didn't have fenders .
When the cub dealers sold the Original you bought the basic tractor and then you could buy additional options like headlights and fenders which the dealer installed . You even had to purchase the mower decks as an extra .
Your fortunate to find one with the original oil bath , pan seat , IH grill emblem and deck as these tend to get lost or broken after all these years .
The hood emblem (bird) comes up on ebay all the time and shouldn't be a problem to find , they also used that bird on some of there full sized tractors .
