I have a few saved in my Mother's old recipe box:
It's made of metal, with a hinged cover. Standard index cards fit in just right, so she copied all the non-memorized recipes on cards, and I managed to get the box after she died. I would guess it dates to the '50s, it's a bit rusty around the hinges. The true Czech foods are mostly handed-down mother to daughter, committed to memory, like dumplings (knedlicky), and some baked goods, as well as meats. Almost as though there were secrets unwilling to be kept in print!
I'll look through it, and get back.
