Easier to measure the inductance and select a similar standard part. Should be able to salvage something that will work from a junk TV or monitor. The wire doesn't have to be identical, anything close will work as long as the core is similar. In a pinch you can make Litz wire by twisting together a dozen or so strands of ordinary enameled magnet wire using a drill chuck.

Lacking access to a L/C meter, you can sub in something that looks close and give it a try. Either it will work, or you won't be able to get the width adjusted within range.
