Stumbled into this ladies Monark that appears to have been fabbed by AS & Co. The steel identifier plate attached to the bottom bracket underside indicates a Model# 4418 and Serial# A6308162 and I'm not able to find much about it. A little help with the date and possible worth would be greatly appreciated. The rear hub is a New Departure, with a grease port and the front is a Bendix. Everything except the tires appears to be OE. Thanks!
