>The seller thought these bronze hammers are Piano Tuner's tools:

I can't say what they are for, but I don't think they are tuner's hammers
(tuner's wrench, tuning lever, and probably several other names are used). I am
most certainly not a piano tuner, but I have seen the inside of a lot of
instruments and can't see how these would fit any tuning pin, which are usually
a male square to accept a four or eight point socket.

I'd love to know what they are for, and how they are used, especially if they
they are a piano tools.

I see no reference in the Studley chest inventory to a tuning tool (1993 FWW
inventory), and don't see anything similar in the photos, but I don't know that
this provides a meaningful data point, as he worked wood and felt (based on the
tool inventory), and I would imagine stringing and tuning was well after, and
done by a specialist as it is today.
