I suspect you cup was manufactured by Wood & Hughes of New York. If your presentation cup has a date that will help identify the year it was made. They operated during the last part of the 19th century.
That would be inconsistent with the date on the cup which is 1841. Was Wood & Hughes operting that early? The cup was presented at a NY event.
I believe the Wood and Hughes Silver Company opened in 1833 when William Gale, Jacob Wood and Jasper Hughes started a partnership.
