Not knowing what tools you have, nor what your experience level is, I would suggest fabricating it using sheet and/or wire. Using a jeweler's saw or shears, cut out a strip of metal of the necessary length and width for the band., solder the band and round on a ring mandrel. Do the same to two pieces of wire slightly larger around than the main band. Cut a srtip for the center spinner, texture, solder and round. Using a dapping punch or a ball bearing of a circumference slightly larger than the inside diameter of the main band, and a steel bench block or some other flat steel surface, place the band on stand tap the ball so as to flare one side of the band. Place the spinners on the band and flare the other side and finish. This procedure assumes you know how to do the soldering necessary to make the bands. If not, this would be a great time to learn.
