Help Identify or Date Item F walter Lawrence

This is a cup that I have had for years. It is stamped F. Walter Lawrence. and has a number as well. It has a partialy scribed verbage but its cut off by the spout. Any help in dateing it or any other iformation would be great. Its in good shape, the flash makes it look worn.
