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 an accurate answer, I need a clear, close-up of the marks.
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 "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 am not ignoring your question. I am having great difficulty locating the mark JLS anywhere.
I will continue looking. Since the L is larger in the middle, the name of the firm is actually JSL.
So far, I have not found it in any of my reference books or reference sites. When I have found pieces with the same mark, the owner/seller does not know the maker either.
I will try to get back to you this evening.
The silver maker's name is ***** ***** it is not to be found.
Unfortunately, I cannot find an accurate answer for your question. I will release your question so that all the other professionals can choose to answer you with accuracy.I want you to have the best answer possible. Releasing your question is called "opting-out." I will not be able to respond to you once I opt-out.I am very sorry.
