This Wilrite, from the 1920s, has the gold-filled overlay over bright yellow celluloid. The gold overlay is complete and very clean (the yellow of the pen makes the gold look silver in the photograph). The yellow celluloid shows some wear, but it is intact and complete. In addition, there is a small green end plug, most likely also celluloid. Nib is a tiny Peter Pan, which writes a nice fine/medium line with a little flex.
