It's a real novelty to see one in the original all wood and wire crate like that from the days before plastic, cardboard pallets and covers. Yet on the other hand with the rust already on it, it is just going to continue to deteriorate if in a place with any humidity in the air.
I'd probably disassemble the crate in a way I could put it back together and at the very least give it a good cleaning or more likely refinish it back to like it came out of the factory.
I've never been one to subscribe to the idea of Patina on my antiques adding value.
