This whip could be carried by a smaller woman or a youth.

It has an antler or staghorn handle.
There is a silver button on the heel of the staghorn which is stamped "Swaine & Adeney Ltd., London".
It has a silver collar with ribbed edges.

It is hallmarked London , the date stamp is too rubbed to read, the shield shape would suggest the 1970's. The collar is stamped "Swaine" and "Fibreglass" .

The shaft or stock is covered in pale brown braided thread. 
The whip has its original stitched keeper in leather.

It has a fine braided leather thong with a red cord lash.  The thong is finer than most modern thongs. I do not think it is suitable for cracking.

Dimensions : Staghorn handle : 5" (13cm), Length (not including keeper) 16½" (47cm), keeper 7" (17.5cm), Thong not including lash 42½" (108cm)
Weight 240g (8½oz)
