Victorian ? Large Sterling Manicure Set - w/Provenance

I purchased this sterling manicure set in Santa Fe a few years back. At the time I purchased it, I was told that it had belonged to Lee Krasner, the wife of Jackson Pollock (and a terrific artist in her own right). Of course, the provenance cannot be proved, but I thought that that was interesting. Each piece is marked Sterling, and has a mark of a "W" within a circle. The box looks Victorian to me, but I am not sure about that. T is a watermark across the front of the silk or satin brocade box (which I believe is original to this set). The bottom of the box is covered with a blue paper, which is blue, and I don't know why it is blue (but it looks like the color has been wet and may have run). This is a lovely set with an interesting possible provenance. If any questions, please send an e-mail and I'll attempt to answer as best as I can. By the way, the little sterling lidded jar is glass, and it is in good condition, with no cracks, chips, etc.
