If was sent to the groups.io then it will be in the archives.  If to Blacksheep, then lost completely - I don't save every Blacksheep message

It's the full extended header contents format I'm after.   It is essentially a .txt block  containing the resampled data rate, the number format  and other info.  The "other" info is not essential  and I left it out of my prog of a while ago.   The text block is embedded within the .WAV as another RIFF DATA block and is only read by software designed to read that format.

It really would help if people posted to the groups.io now, so messages are automatically archived.
It's not Yahoo anymore, so those who refuse to have anything to do with Y no longer have an argument.

Well, EA5DOM sent a .wav file in his email of the 12th DEC. With this wav file you can 'play'. It contains an EbNaut message that you can try to decode. I don't know how to answer your question better.

Could someone also please document the format of the custom .WAV file generated to read into the decoder software
A couple of years ago I made a custom LF receiver that managed to successfully receive some Ebnaut signals on 137kHz.   I had some details of the custom file format needed, but have now lost them.  So all that's available now is my original source code, and FAIK it may not be as complete as it could be - and things may have changed  It just worked back then.
