I am looking for the value of a solid oak extension table I inherited from my grandmother. Under one of the chairs from this set is a hand-signed tag with the signature of John Breuner.
The table and chairs look in good condition from what I can see from your photos. I would say this would be worth around $1500 to $2000. If you're looking to insure the table in case of a fire or damage I'd talk to an antique dealer in your area to get a better estimate for the insurance company.
On liveauctioneers.com, a set by this manufacturer had a starting bid of $1000.
