Details:
Is anyone able to identify the maker and model or code number of this collet from a French made machine. It is a fairly typical shape and the lower 'collar'is stamped S3726 which may be the type of collet (such as 5C) but so far an internet search has come up with nothing. What I think are the important dimensions are show in one of the photos. Any help will be gratefully receieved. Thank you.
