Filigree Pens - These pens are very attractive. They normally have black hard rubber caps and bodies but rare examples are found with red rubber. Even rarer pens have mottled or rippled bodies. The pens pictured include a slip cap Secretary pen #412 1/2. A silver overlay #452 and the #0552 gold filled pen at the bottom.  The bottom pens have the bamboo pattern used from 1924-1933.
