Sorry Catherine, afraid there's nothing in the marks to indicate age. As you will have already read, the company was in business between 1901 and 1985. The design of the toast rack has an Art Deco influence but I suspect that timewise, it may be a little later than the 1930's . My best guess is 1930's to end of the 1950's. I recollect my parents having been given a great deal of silver plate items similar in design as wedding presents in the late 1940's.
Regarding the crystal dishes, I don't think they are salt cellars, but rather butter pats.
