Extendable Table with Bun Feet

There are numbers on the pieces of wood and this goes together like a puzzle. I didn't measure the bun feet but cannot find any
as large as these. I would love to know, the era of the table, what kind of wood this is.
I think it came from Europe.
It measures 32" x 33" base, when assembled 36" x 36" and when extended its 59.5" x 36" inches.
That's all I know. Much appreciate any information about this.
