Gee that's going back a while to the old spirit duplicators - purplish ink
as I recall, that disappeared quick smart. Based on a metho formula I think.
In those days up market duplicators were the old wax stencil Gestetners.
Their print didn't fade but the paper was often quite high acid.
About the 1960s I think?? They must have disappeared by the 70s though
