What our customers say about us

Image by Matt Seymour

Coln has done a SUPERB job with restoring an old Hobson Claudel carburettor from a 1936 Armstrong Siddeley car. They were extremely caring and responsive and went the extra mile to restore this family heirloom. I can't recommend them highly enough. Many thanks to the ever responsive Ian Soanes at Coln. Great job!
