Cub Loboy Seat Question

[Jimmy Joe]

I have a friend who has a loboy tractor the serial number puts it in as a 1960 model. When I search this tractor I can't find one with a seat like this one has wondering if anyone has seen one like this was it an option or maybe added later or am I missing something in my search?

Someone has replaced that seat. These are the 3 that were available through IH over the years. CASE IH | Schematic, Manuals, Specifications and Diagrams for superstructure, seat and platform | MyCNHi US Store

Thank you I was thinking the same but wanted to be sure.
