OTCO silver/crystal tea light holder?VINTAGE ITALY

I have a piece that I’m not familiar with here. Originally bought from an estate sale I am not sure of the origin or history behind this piece the only other things I could find about otco Is that some crystal was made with 24% lead but I’ve cleaned the silver holder that is with this item and I believe it is silver plated if not pure silver it’s very light weight and it was easy to clean the black tarnish that crust over The top layer. Sold in as is condition packaging will be secured no breaks
