Thank you for the replies. I will look at the hub for the date. I am fairly certain they are original to the bike. The reason for wanting to know the date of the bike has little to do with parts and more to do with how old my mother would have been when she rode her bike. Purely for sentimental reasons. I apologize if the the title of my post is lacking. I am very new to the world of bikes especially bike forums. I will try to be more specific next time. Thanks, Leah
