Need help - Marks on back of Quadruple Plate Silver Platter

Any help identifying these marks would be greatly appreciated. I've Googled the info and searched this site high and low, with no luck. Thanks!

I believe that's a mark used by the Middletown Silver Plate Company, Middletown, Connecticut. After the Middletown Plate Company became part of International Silver in 1899 some of the old employees started up the Middletown Silver Plate Company. They were in business till roughly 1940.
