Matching pair of 19th century balloon back chairs that were in my family for 50 years, always well maintained. Second one just had the retaining pins replaced holding top curved piece of back, making it very strong. I have seen similar chairs in the Oldest House Museum, Key West, and the Civil War Herlong Museum in West Florida. I do not know if these are pre 1850 or post 1850. Any advice to better date is appreciated. Local pickup can be arranged in Sebring  or Venus Florida. Shipping given is to Miami Florida. Please give me your address for correct shipping cost.
