What I found was that your vase may have been made by Ahronsberg Bros, Birmingham !! They used two marks A and B in separate squares 1896 to around 1900 and after that A and Bs each in separate squares !! Your mark may have the small s and we just can`t see it !! They made holloware vases, flower pots and novelties !! Look at the top insignia and see if it looks like a scroll work AB or ABs !! I couldn`t make it out at all !!
