Top quality, made in Italy. These Lambretta clutch compressors are for compressing the plates and steels on the cassette part of an A F Rayspeed clutch so you can undo the allen bolts safely under even pressure so you don't snap the cast 'tangs' on the clutch bell - this will definitely happen without the use of a clutch compressor as they seem to be made of cheese!
 These are an invaluable and necessary tool when stripping one of these types of clutch.
 
This compressor can also be used on the Cosa type Vespa PX clutches.
