The company started out as Wilson & Southern in 1828 on Edward Street, in 1840 they were on Solly Street and Wheeldon Works.
In 1847 Wilson retired and Samuel Richardson teamed up with Francis Southern and changed the firm name to Southern & Richardson. In 1912 the company became Limited, so any items marked with LTD would be after 1912. In early 20s, they merged with Needhan, Veall & Tyzack for a short lived adventure.

That said the only trademark registration for Shaveesi (not shavesi)that i found was from 1909.

Interesting that the information i found claimed that the company became Limited in 1912, after posting i realize that the trademark registration from 1909 had the name Southern & Richardson Limited. Perhaps Mr Miller can clear this up!
