Maker's mark starts with K - help ID please!

I have searched and searched for information on this hallmark. It’s on a miniature sterling tray (pin tray?) that measures approximately 5-3/4" by 3-3/8", It sits on four ornate feet and has twisted handles. The backs of each of the feet are stamped “118.”

The maker’s name appears to start with a K and end with an R (they are attached by a swoop across the bottom), but I just can’t make it out successfully and find nothing in my research on-line to help me.

Any help would be greatly appreciated. Thank you!
