Tiffany & Co 925 Sterling Silver Purse Pen

Vintage Tiffany & Co sterling silver ballpoint purse pen. 4 5/8" long (closed) and a 1/4" wide at the top tapering to 3/16" of an inch right before the pen tip. Pen has a very nice cross hatched diamond pattern with a smooth band, marked "Tiffany & Co. Sterling Silver 925". The pen cartridge is empty and does need to be replaced. Carefully hand polished with Weiman's and cotton, but it could use a professional cleaning. Good vintage condition. The last two photos are of the "Anson Med. Blue Refill ...H." I see these available on Amazon.
