No text, but a visual code

It was the closest I had seen, with the possibility of being timely. I think you would need to find a non printed version. Most i had seen had the zodiac on the outside, separated into three, which didn't match your volvelle layout.

Yours is 'Instrument-maker Gemma Frisius devised a volvelle for inclusion in Peter Apianus' 1524, Cosmographia'

Gemma was then 16 years old. 

Here is one that's not printed, although it might be late too, the eclipses start in 1460.
