From my personal collection, this is a Very Rare Mandarin Yellow and Jade Park Row Vintage Fountain Pen with Gold Plated Trim and 14K Solid Gold Medium Fine Flexible Nib. The Cap end and Finial are Jade Green Celluloid. The Barrel and Cap are ebonite. 
This Park Row is fun to write with. I use it often and clean it after each use but there are still traces of ink. 
*The service included dis-assembly, distilled water cleaning, towel dried, tested the nib, new ink sac installed and chalked with re-assembly, soft cloth buffing. This fountain pen works beautifully, it was tested and rinsed.
