Antique wing chair

Hi, I have had this chair for 6 months. I recently posted it on trade me for $40 however have got a lot of interest for it. It seems to have hand carvings and got told it is an antique wing chair.

I love sitting on this chair as the wing add extra comfort. It does have a tear left arm and missing a button. Other than that it is in great condition. I am not an expert with this but just came here for advice.

Just some advice on what era etc.
