I don't really know anything about vintage bicycles, but I found this in my mother-in-law's shed and wanted to restore it. She said she is pretty sure she got it when she was around then years old, give or takea year or two; she is now 61. The stamp on it says M.O.T 11x7 592836 . If anyone can help me find out what kind of bicycle this is I would really appreciate it. Thank you!
