Hello, can anyone help me identify the Sponsor mark on two pieces of silver jewelry with Sheffield hallmarks? Sponsor mark MTP in a rectangle and the years are 1992 and 1993… Hallmarks are Tudor Rose, Lion Passant and letter S for 1992 and Tudor Rose, Lion Passant and letter T for 1993.
Thanks to anyone who can help.

It’s not listed on the standard reference sites, so you might have to contact the Sheffield assay office to help pin it down.

Sparkler, first you help us by posting a photo with the signatures to decipher.

I have done this very thing but may need to try again. Thank you though.
Bartholomew, this photo of a green brooch looks exactly like my brooch except the date letter on my brooch with a green stone ( aventurine I think) is a T for 1993, not a Q as this one you posted. but it is a clearer photo of the MTP sponsor mark than mine. Thanks for that.
I am adding a second photo of my silver and lace agate brooch with the date letter S, as my first photo was a bit blurred. The MTP mark is much clearer on this new photo and shows the sponsor letters in a parallelogram rather than a rectangle. Sent a second email to Sheffield Assay office to find out who this sponsor mark is registered to so hopefully I can share this info once I hear back.
Thank you for helping.

I have included sample photos to clarify the topic…
S - 1992 (according to English Silver Hall-Marks edited by Judith Banister 1995 BELASCO).
Send me, please, whole item photo.
Enquiry solved. Sheffield Assay office archivist has supplied the name for the sponsor mark on my brooches. M T Pendlebury from Cumbria. I attach a photo detailing this for your review. Interestingly, there were two sponsors registered at Sheffield with the same initials around the same time.
