Hi Tentman,

I have used this company over the years and do a first class job.

An extract from their site.:

"We also specialise in the repair & service of all optical instruments including Binoculars, Telescopes , Rifle Scopes. Our workshop has a unique Invar Base Line for traceable EDM calibration."

I hope that this helps,

Cheers,

Jeff Gray
