240v Portometer Electric meter issue

[Caladh]

Although the lead works the meter reader is not going round. Result, some may say! I'm wondering if its repairable. It appears to be sealed and I'm wondering that there must be a replaceable component that make the meter turn etc

Tried looking up the company for more info but they don't have a website or any communication apart from telephone or mail. No info on products.
Should that unit have a blue cap on the right hand side? does it have a dial of any sort, I assume it measures Kwh? Knowing that if you try and open some of these types of units you will destroy any IP rating. How old is it? I would suggest that maybe a replacement is in order!
I did find a vague reference Dated 1989!
