Vintage Mappin Brothers fish serving set

Antique Silver Plate Master Fish Set Knife & Fork. Mappin Brothers makers mark. From what I could find in my searching, looks like these are from late 19th century or possibly early 1900''s. I believe they are silver plated with celluloid handles. Some abrasions and tarnishing from age. I didn''t want to try to polish them up, not knowing what I was doing. No case. Can insure shipping at your request for an additional charge.
