GTD info.

I'm looking for a Greenfield Tap & Die catalog or site.
I'm coming up empty on trying to find dates on these pipe wrenches.

According to the1921  trade mark filing, G.T.D. used  G.T.D. in "interlocking teeth" since 1915 ( https://books.google.com/books?id=JqSQAAAAMAAJ&dq=greenfield%20tap%20pipe%20wrench&pg=PA380#v=onepage&q=greenfield%20tap%20pipe%20wrench&f=false );
<a href="https://books.google.com/books?id=JqSQAAAAMAAJ&dq=greenfield%20tap%20pipe%20wrench&pg=PA380&ci=57%2C737%2C424%2C333&source=bookclip"><img src="https://books.google.com/books?id=JqSQAAAAMAAJ&pg=PA380&img=1&zoom=3&hl=en&sig=ACfU3U0VYqVxRE87RLf0mxftGGZxoUEXRA&ci=57%2C737%2C424%2C333&edge=0"/></a>
There are several succesive Greenfield Tap & Die  trade marks there, "LIGHTNING," "O.K.,"  "GREEN RIVER," etc.  -- with various dates for claimed first use going back to the 1870s for a couple.
