This is the front brake drum and hub assembly, listed in the catalog as 37-3658 (also seen under the earlier W3658 form). It's front wheel gear, part of the front brake and hub setup that the wheel spokes lace into and the brake shoes work against.

The catalog places this in the front wheel section of a supplement tied to the 1971 250cc replacement parts catalogue, with appearances running 1971 to 1973. This is a drum brake component, cable-operated, no hydraulics involved.
If you're trying to match this to a specific machine, the record here points to the 250cc range for these years but doesn't spell out an exact model. Call the shop and we'll confirm fitment before you order.
