Chronometric Rev. Counter refurb in UK

Can anyone recommend someone reliable in UK to entrust with a chronometric Rev.counter? I sent mine away 18 months or more ago prior to putting my Triton together. I’ve now fitted it and it won’t work correctly and I can’t return it to the person I spent a lot of money with. I don’t want to go into why not, but I don’t want to make the same mistake again.

A while age (10yrs?) I used these guys - I was happy with their work.

They have ceased trading as of about 6 weeks ago. I was in contact with them.
