Something is only a fake if is being passed off
as something it is not.
Theoretically, sold as a Caithness Ltd. edn. weight, with a wfs cane in it, it could be considered a fake in this instance.
But given Caithness made weights for wfs, and the large collector base there is for a very restricted number of very high quality weights ever made.... not one I reckon you have very much to be complaining about.
