DescriptionBrass, German silver, tuning slide at second bow, three Stölzel valves (1, ½, 1½), spring in barrel, clapper key for left hand.
Two tuning shanks for B-flat and A, two tuning bits, and three crooks for A-flat, G and F. Two mouthpieces, one of silver (probably original), the other of German-silver (not original); original oil container. Original embossed leather-covered case with red velvet interior and compartments for every accessory.
A crook or coupler for E appears to be missing, because the markings at the valve slides suggest that this key was formerly present.
George Macfarlane's involvement in the invention of the clapper key remains conjectural; it has been stated incorrectly that the clapper key is described in French patent no. 2627, issued to Macfarlane on December 10, 1845. It thus appears that the inscription Mc. FARLANE'S IMPROVED might be an advertising vehicle employed by the Köhler firm, similar to the inscription HARPER'S IMPROVED.
