Wooden board with inscribed rotating parts using an unfamiliar alphabet

Apologies for the far view photo quality, they were taken and sent to me by my technology impaired mum.

This thing has been sat around in our house for >20 years, my mum inherited it off of her sister when she passed away and it's been collecting dust in the attic ever since. No manufacturer markings present, or any other distinguishing marks from what I can tell. I can get more photos taken if the 2 provided aren't sufficient.
