The Wayne or M&S 80 series has 23 different pumps. The 1T-Z (that's a 1 not an I) means it was a standard computing pump with a cable pull hose and a Gilbert & Barker meter.

I have color ads, color sales literature and a parts manual available for this pump. It is also shown on pages 331 to 333 of my Gas Pump Identification book.

Norton advised me not to use PMs so I shut it off, email me at jhsim@swbell.net if you have any questions.
