UNBRANDED T IN A CIRCLE MERCURY MARK SPACE SHIP

I used to be a big collector of T in a Circle/ Tai Hing plastic toys.

One I haven't got is the Mercury Mark IV Space Ship like this one I saw online.

Its a lovely thing but this particular one appears to have no branding. Not T in a Circle/ Tai Hing, nothing.

I can see wording on the battery cover which I think says Made in Hong Kong.

Have you anything like this readers?
