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.
One of my specialties is identification of silver.
I think I know what you have; but, to give the best answer possible, I would like two clear photos.....
One of the set and one of the marks on the bottom.
You may need to use the macro function (flower icon) of your camera to get a good clear photo of the marks.
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 "attach" or "add" link or "paper clip" you see on your reply page.
PS: Meanwhile, please don't rate me until you get a full appraisal and a value from me. I mention this because you may get random prompts asking you to rate me before I've submitted an answer. Ignore them. They are automatically generated by the system (it doesn't seem to be able to distinguish an answer from preparatory back-and-forth and information gathering) and don't come from me.
