Monster Oil Trumpet Care and Cleaning Kit

This set gave new life to my old B&H cornet. Since the cornet had been stored for several years I had to give it a complete overhaul; slides, valves, leadpipe & mouthpiece. The Monster Kit proved itself to be all-inclusive. All I had to add was water and dish soap.
Useful 14-point instructions incl. Luckily for me on water resist. paper. The oil and grease, on some parts in combination, has made slide-action smooth and valve-action sparkling.
