milk glass 4 small cups & saucers

I found these and thought they were sweet. 4 coffee cups and saucers. The makers mark appears to have 2 elk and numbers eg 10. I have tried to find out the maker but I've not been successful. Hoping someone else may know who made them and from what time. I did try and etch the 2 elk logo with pencil for photo id purposes. Was there any more made... i would assume a missing tea pot.. coffee pot creamer and sugar? Would like to add more... but don't know name of maker or pattern to search for other items. Please help.... and thank you for this amazing resource.
