Hello,
On the assumption that the much worn marks on the silver top show it was sent to the London Assay office by WHW in 1894 there are two candidates in William H Walter and Walter H Webber.
John Culme's book on London Gold & Silversmiths indicates their two marks were almost identical in 1894 and both retailed silver topped bottles. With the wear on the WHW mark it isn't possible to differentiate.
