Is there a manufacture date on the 9100 operator somewhere?

There is an inspection sticker placed on the Motor of the Motor/gear box assembly and also on the top of the transformer on the control box.  This inspection sticker has the manufacture date, which is a four digit number, the first two digits are the month and last two digits are the year.
