International Silver Company Vintage Small Teapot, Sugar bowl, creamer and tray

International Silverplate Company Vintage Small Teapot, Sugar bowl, creamer and tray. I believe the tray is made in China and the tea set may be made in Italy. The tray I just added to the tea set! Platter Diameter 9.75".  Small teapot serving pots, could be fun in kids playroom as small in size😊.
