S.K. Pierce & Son Dining Set - two leaves, one captains chair and 5 side chairs

Looking for more info - thinking this set is circa 1898-1920 or so. SK Pierce & Son label states Brooklyn NY. I bought it for 500 - has two leaves and custom pad. We use it daily - very sturdy. Chairs hold my 350 lb mini-mountain of a nephew. Has had minor repairs to underside of chairs and table top was restored. Any info is appreciated.
