I sent a group of .wav files by FTP to a company for a
short reprint (100) of a CD. They had received the
original files by a physical master but the business
subsequently changed hands, and the new owners did not
know what happened to the master.

When I sent the files, I did check file sizes to be sure
the uploaded files were the same size as those I sent. I
have checked the files I used for the upload, and there
is no problem with any of them.

If you're saying that you checked the file sizes on the server and they
matched, this is really pretty strange. I can imagine that the server might
allocate space for the upload right up front. However, there should have
been some indication that the transfer was not fully complete.

Unfortunately, when I got the CD, the third song was
truncated - a 3 minute song simply stops at 41 seconds
and goes to the next track. I tried several players, and
all had the same issue. The only sonic event was the end
of the music; there was no click or pop or anything else.

I assume that a file which was "broken" in transit would
not serve for anything.

It's possible for a FTP program to transmit a partial file. The nature of
the protocol is that the sender should get a negative response indicating an
incomplete transmission, or a positive response indicating a complete
transmission.

I cannot think of a problem which
could have caused this result in the FTP process,

I've seen zillions of incomplete FTP transmissions, for reason ranging from
broken connection, to a hung connection, to the FTP server disk getting
full.

However, in every case there was an absence of an expected positive response
at the end of the transfer.

In the case of a hung connection, I've had to force the FTP transfer to end.
Pretty rare these days.
