In this 1993 mailing list exchange you can find Szabo talking about Hal Finney in good terms in reference to 'digital cash':

Also in this forbes interview with Finney, I get the impression he was rather close to Nakamoto and he indeed was instrumental in the improvement of the early bitcoin client:

Also Finney was the the first one to answer to Nakamoto here:

It just seems to me that both Finney and "nakamoto" and Finney and Nick Szabo (Nicholas J. Szabo) were really close.

I came up with 'Nicholas J. Szabo' through his tenure at George Washington University. (e.g. https://www.idmarch.org/document/The%20Spirit%20of%20the%20Laws/doyl)

A plausible candidate for this is:

Which would make him 57, roughly same age as finney. there seems to be two more people in that address: another nicholas szabo aged 82 and a maria k szabo aged 78. so perhaps he just used his parents address...
