Anyone with any tips? TIA.
If the file I have is correct it is 165,557 bytes size.
I tried
https://www.jpegmedic.com/tools/jpegmedic/ and it could not find any form of any image in that file so I would guess that the file past recovery.
Presumably you are unable to go back to the source from whence you found it though you could try
http://wayback.archive.org/ * to see if it is available from there or try the cache on your own machine though likely gone now.
* I couldn't get
http://wayback.archive.org/ to open at the time of trying but I have used it in the past to find something that has since been removed.
