Pat, those old plastic sewing boxes like yours sometimes show up on eBay. I have several that I've gotten from eBay and an very happy with them. You just need to keep an eye out on their listings for sewing supplies, notions, misc. lots etc. I think they're called Wilhold or something like that, but it's pretty easy to find them if you just check the EBay sewing listings every couple of days.
Just be sure and check the pictures to see if they have any cracks, broken latches etc. I've seen them sell for as little as $5 and as much as $35. Sometimes you will find the boxes that that company made to hold thread and patterns as well.
