Hand folder and hand stitched will be easy to determine. The fabrics will be the clue as to it's age. and.. it is as old as it's newest piece used.. fabric pieces were different in the 1970's.. not much cotton then.. look for trend fabrics, 1950's 1930's.. how frail is the quilt? serf the Internet for fabrics of specific eras. those that are replications.. Usually they are heavy quilts without batting. good luck !
