Vintage Bread Box with Glass Jars

Drop-front wooden bread box I got from a yardsale a while ago. Clear glass window in the front with dull gold lettering on it saying "BREAD", with roses underneath. Inside, there's four hexagonal jars that fit perfectly, and their lids seem to be the same wood as the box itself. They say "Libbey of Canada" on the bottom. I looked this up and found many hexagonal jars, but none with the same lids that mine have. I'm not sure if these originally went together or not.  I'm not sure when this is from, or whether it's an actual vintage item at all or simply designed to look like one. I don't know much about it at all. It's not cheaply-made, though. Very durable and heavy, and has a feel to it that just doesn't seem like something modern.  I did a little research and found some images online of bread boxes that looked identical to mine (aside from the colour of the lettering being different on some) listed as "vintage". I just couldn't find a year, manufacturer, etc.. mentioned anywhere. So, I'm hoping someone else might have some idea.  Thanks !
