I am trying to find out what series & date a knife I found in my grandmother’s belongings. It is marked with 1847 Rogers Bros AL & a logo… I also need to know how to clean it. I have search the internet & the closest I can get is the Siren design. Thank you in advance for any help.
The only example close to it… From the Brooklyn Museum, Rogers Bros. Siren Pattern. Image taken from Brooklyn Museum website.
