I don't know too much about this company, but I can tell you that it was started in London by a man named John Maple in 1841. Now, from what I remember, his company started stamping an LTD. mark after the Maple & Co. mark after the year 1891. This means that your piece pre-dates the 1891 mark. I think the "S" stamp at the end means that it is "Sheffield Silver." I know this probably doesn't help you much, but it may be a start. Good Luck!!!!
