Email received from Jim Hagerty WA1FFL:
Hi OM- I noticed a card by W1AGI- my grandfather! This is the only one in existence that I have seen. He died in 1949 and I never knew him. He never got a degree but taught himself electronics by building and taking courses at Brown University. He was also an expert golfer and swimmer and performed in musical theater!
The amazing thing is, not only did you have his card, it was one of his earliest- I think he went on the air about 1928-9. He worked a ZL with this station and I can scan it and send that to you as well- I still have the card. But your card is the only one I have seen that he himself sent out. I looked up that tube- a 210- and apparently many hams used the UX210 for 1-tube transmitters back then. I do know that he built a modulator in the early 1930's and ran about 160 watts input on phone.
73 and Many thanks- Jim WA1FFL

 

Here is the ZL card that Jim talked about:
