Help finding replacement nozzle

Hi all

I inherited a creatbot dx plus from my work place. They claim its broken, I think it just needs a few parts and some love.

Anyway for the life of me I can’t find a replacement nozzle the right size and I’m sick of spending money on wrong extruders. Is anyone able to help me determine what this is so I can buy a new one online that’d be great!

Thread Diameter: 9.7mm
