Hello and welcome! My name is Doris.I have been an antiques collector, dealer and appraiser for over 56 years.I will be pleased to help you.
To give you the most accurate answer, I need photos - at least one of the set and a clear, close-up of the marks.
I also need the measurements of the tray.
If you cannot get a good photo, then sketch the marks and take a photo of the sketch.
To send photos you may use the "reply to expert" in the blue box link on your reply page or the "paper clip" found in the toolbar you see on your reply page.Please do not send in ZIP format. The jpg or jpeg format works best.
An explanation of this method can be found here:
I cannot help you over the phone with an exact, accurate answer. Much depends on the style of marks.
I have been a collector, dealer and appraiser of English silver since 1957.
I am an English silver specialist.
An accurate appraisal cannot be given here without photos.
