stolen 1967 Schwinn Collegiate

This is a women's 1967 Schwinn Collegiate. This bike is in fairly pristine condition. It has almost entirely original parts. A front basket was addition, but it has all the original chrome fenders, handlebars, lights with generator. It was U-locked to a rail through the tire and frame. The thief sawed through the rail to get the bike, but would not be able to ride it away (since the U-lock would keep the wheel from turning). Please help me find it!I don't have proof of ownership, but my boyfriend has its "mate". We bought the bikes as a pair and the serial numbers are very close (but I can't remember what the actual number is).
