Hadcock Tonearm - 1977

[Redox]

Hello everyone. I have this Hadcock tonearm that was removed from a Fons TT. It was fitted with a Decca London cartridge. I think it may date from around 1977.

Does anybody know this model?

I have included a photo of it working, but I would say that it needs a refurb?

I am going to try and sell it, I'm unsure of the value.
Any suggestions?

Thanks for any input.
