Float Tickler Pin Set to Fit Original Amal Concentric Carburettors

This is a 4 piece Tickler Pin set of the type fitted to late type original Amal Concentric (Series 6 or Series 9) carburettors.

Note - an original Amal Concentric carburettor is shown in the photo for reference - but that is actually fitted with the other (early type?) tickler.  The kit has a top tickler that sits externallly and allows it to be more easily found using finger or thumb - which I believe was of the type used on later models
