Smiths 4" cable driven 3.55:1 ratio rev counter from a Spitfire (Nov 72 to Nov 74) but please double check exact fitment - Smiths number on the face is RN 1326/00. The instrument has been 'fully' stripped, all mechanical parts have been ultrasonically cleaned/inspected and any worn/damaged parts replaced where necessary. The casing has been blasted/painted and the bezel, glass and seals have been replaced. It has also been bench tested and recalibrated (including remagnetizing the magnet as appropriate) so I can confirm it works correctly. All in excellent condition. Outside diameter of bezel is 104mm, casing is 98mm diameter.
