Can someone help me date this Reed and Barton tea set?

Hi - I'm hoping someone can maybe help me date this set. This came from a collection of silver and silver plate that ranges from 1810 - 1900. Only one of the pieces is marked; it's very faint and the different lines run over each other; I simply couldn't get a picture of it - but it reads "[illegible} PLATED BY REED & BARTON 2220 GT". I was hoping someone might recognize the style. Thanks so much for any help.
