Can anyone help me with the notes-to-holes matrix for my harmonica?
I have a Hohner Comet 80 C/F mouth harmonica. I did not practice much, although I have it for several years.

One (OC ?!) reason for this is that I do not know the notes of each hole. And my mind is very engineering-ish, even when it comes to arts.
So the question is: can anyone help me with the notes-to-holes matrix for my harmonica?
I expect something like this (just example from the Internet, most likely not my harmonica):

I searched the net a lot (to the extent of my abilities), without any relevant success. I even wrote (and sent) an e-mail to Hohner, but they never answered.

Your Comet could be up to 50 years old.It uses the tremolo system, easily Googled. Holes 7 to 13 produce a full diatonic major scale. Be aware that your H is a lot of people's B (si or ti).
You can map it yourself, as each hole produces one note from the diatonic scale, whether blown or drawn. Block off surrounding holes, and listen to each hole in turn. Some adjacent holes produce the same note, blown and drawn. Notably 4 and 5.
If indeed it is an '80' model, there will be holes both sides, probably producing diatonic C one side, diatonic G the other. Having double holes should mean it plays octaves, when both are blown. Making a much stronger sound.
The 'Comet' name was used for several different harps, 16 (32), and 20 (40), and 2x40 (80) holes/notes.

Just blow and suck and figure it out in a piano or other instrument. You could even post a recording here and someone could tell you.

Following the advice (and hyperlink) from @chasly , Hohner ultimately provided the exact information I needed. I only added colors and formatting.
Thank you Chasly!
Thank you, Hohner support!
