Help with exif data from Browning BTC-6PXD camera

[k8ysk111]

Hello!

I'd like to be able to access the MakerNotes and understand the UserComment data for the Browning BTC-6PXD camera. I'm trying to extract temperature data and give unique names based on image sequence number. I can do it with Reconyx cameras just fine and was hoping to get some help doing it with Browning images. I get a warning - unrecognized makernotes, and I'm not sure how to understand the usercomment data.

System: Windows
ExifTool version: 11.74
Specific command line/script: I'm using the PyExifTool wrapper and Jupyter Notebook.

with exiftool.ExifTool() as et:
    metadata = et.get_metadata("./data/IMG_0073.JPG")
   
for k, v in metadata.items():
    print(k, v)

Output:

Please let me know if you would like an example photo. I was unable to attach any.

Please send the sample image to philharvey66 at gmail.com and I'll see what I can do.

Will do! Thank you.

I still haven't received a sample (I don't think it went to the junk mail, but just in case be sure to put "ExifTool" somewhere in the mail to avoid my spam filters)

Sorry for the delay in responding, I was on vacation.

I got the samples.  I can see something potentially useful stored in the UserComment, but the MakerNotes contain no useful information.

Here are the UserComments for the files you sent.  Does any of this make any sense to you?:
