Once upon a time these pieces were part of a Hollywood Regency Feather/Palm Tree Leaves lamp. Unfortunately it must of met an accident and this is what’s left. Maybe you can restore them or use for restoration of your own broken lamp. There are 4 pressed glass feathers measuring 8.25” long x 3” at the widest part, a center glass globe approximately 2.5” wide x 2.5” tall. There’s the cast metal plume holder with 3 intact and 1 missing and numerous washers and cap. I have found a couple of chips on the plumes but nothing that is distracting or structurally detrimental.

The last picture is an example of this style of lamp but it has 5 plumes. Parts could also be used for your own ideas!

As always your satisfaction is guaranteed.
