hello Angela.............Assuming this to be a genuine period piece, than your colour might just be amethyst rather than purple..........I've looked through Gulliver and there are shed loads of variations on ruby and cranberry with some orange and amber, but purple I can't see.
S. & W. did produce a very similar colour shading like your piece, but called it amethyst which faded to clear lower down. A date of something like c. 1900 might be somewhere around the time. I'm not saying yours is an example of this S. & W. style, but just that it looks similar - am sure one of the other girls will have a better idea.
These feet are called pincered work I believe, and yours appear to have a plain ribbing pattern, although sometimes they have a daisy pattern.
But, first I suggest you make sure this is late Victorian - look for wear in all the usual places - your lucky if you have all feet intact - they are so ofter damaged.
