ID for WS on Detailed Motorcycle Bracelet plus appraisal Please!

Hello, I’m trying to ID the hallmark WS on a very interesting .925 silver bracelet. I’m pretty sure that there are only one of these ever made and the fact that it’s a very detailed large motorcycle leads me to believe that either the artist made it for himself or a relative or by special request.Please check out the picture and any help would be greatly appreciated! Thank you

Hello, thanks for sharing. Do you have any information on the piece? Where you purchased it? How old it is? Also, can you include the picture of the inside of the cuff with the hallmark?
