Unknow safe and combination picking walkthrough needed

[the_white_peacock]

Hello and thanks in advance to everybody who may be willing to help me identifying this safe and finding out the correct dialing order.
My dad passed away one year ago, and I wish I could find his safe's combination, since I've got the key.
By manipulating, I'd say it has three wheels, but I don't know if the first input should be L or R.
I watched some tutorials, and I thought I've found two possible numbers, but when I tried all numbers (two by two) while searching for the final one, it seemed like no number worked.
I attach the charts that helped me finding the first two numbers, even if I'm not sure if I read them correctly.
Any hint would be much appreciated.
Thanks

Unknowingly using a gate as a comparison for a high low test, invalidates it. Maybe 30 is not on wheel 1.

[Edit, removed combination because the safe is in use] would be my first try. If it doesn't open, graph wheel 1 around left, 2 at 30, 3 at 40.

Keep us updated and good luck!

Thank you so much for your help!
It's amazing: [admin edit, removed combination because the safe is in use] seems to be the correct sequence. I'm still wondering how you've found the number 20

Anyway, now the dial stops at 93, but any position seems not to be affecting the key's rotation range, that remains always the same, despite of the dial status.

I made a video, to be more clear:

I don't want to force too much , am I missing something?

You're welcome. To discover the combination, I've seen your graphs and made an educated guess.

Now the combination lock is open. Leave it where it stops at 93.

Were you able to unlock the key even without opening the combination lock? Sometimes the key can't rotate completely unless you've opened the combination lock. Then the key can fully rotate and allow to open the bolts.
Have you noticed a difference on how far can you rotate the key before and after?

Anyway, I'm guessing the bolts may be the problem now. Try to gently tap the safe door on the corners with a rubber mallet, while rotating the steel handle back and forth, and see if those bolts move.

I've removed the combination from our posts since the safe is in use. You already had time to try it and memorise it.

Have you tried to push or pull the bolts handle?
