Poco Proof Press Serial Numbers/Dates

Is there anywhere that tells the dates of the Poco Proof Presses? I just picked up a No. 0 #633, curious about the production timeframe! Thanks

The serial number indicates that is was made by A.F. Wanner, ca. 1910–14. https://vandercookpress.info/vanderblog/poco/
