Finally after multiple emails I got a reply from SMOK.

Yep, that's it. Not much but at least it points me to a correct direction. I've taken my M80 apart again and took the display off this time. It revealed a some kind of serial number and I was able to establish that there are 14 connectors on the tape. When 'googled', the serial number doesn't bring up anything but there are some displays over there that look like might work.
The only other issue will be to solder it in without breaking.
Hopefully I'll be able to post some successful pictures shortly. I know that this box is not that expensive but I won't be able to forgive myself if I don't try. It was a very, very long time since I have soldered something so tiny. Good luck to me [emoji6]
