1893 Antique Sterling Silver Burns Patd Serrated Bread Knife Rare Unique England

I couldn’t find any knives like these online. Joseph E Burns is from England. This is a 1893 bread knife (per google) PATD EDGE NO. 1435514 The blade is stainless steel and I believe the handle is sterling silver, maybe silver plated? The handle is heavy weight of 77.13g over two Troy ounces. It’s been in storage.
