This looks similar, but not identical, to a Sonoma Swing Wallet 4965 from 1995 that I rehabbed. Hyacinth kindly authenticated the swing for me and provided a catalog photo/entry. See the before and after pics and the catalog pic at the link below.
Be aware that the swing contained metal D rings to attach a strap that was missing, so I substituted a chain strap. Even if it is the clutch, it might also be missing a strap.

Note: for some strange reason I kept calling it the Sonoma Sling but it is a Sonoma Swing!
