Wanted - Autolock collet

[Andy B]

A long shot - but someone may know of one lurking in a dusty cupboard....
I need a 25mm collet to fit a Clarkson Autolock chuck for my Tom Senior mill.

The 30INT chucks were called 'large' by Clarksons - but they used a smaller size of collet than the 'large' chucks on the 40INT tapers (which are commonly available) - hence some people call these 'medium' collets!
Confused?
I've uploaded a catalogue extract here
The one I need is a '40097' - the outside diameter is around 1 3/8".

These would also have been used on R8 taper machines (e.g. Bridgeports and clones) - but they seem to be very scarce.

Any leads appreciated.

Norm,

Have sent you a private message.
Has your collet got a groove in the edge of the 'wings' - that indicates a metric size.

Thanks,

Andy

Norm - have sent you another pm.
I need your contact details - and ideally a photo of the collet just to conform it is what I'm after.
