Letter Opener, Standard Steel Propeller Company Promotional Item 1920's (pre-Hamilton)
Here is a beautifully-presented chrome Letter Opener promotional item from the Standard Steel Propeller Company of Pittsburgh, PA. In 1929, Standard Steel Propeller merged with Hamilton Aero Manufacturing, thereafter known as Hamilton Standard. So our assumption is that this item was offered prior to 1929, since the decals on the letter opener state "Standard Steel Propeller" and not "Hamilton Standard"
It is in exception condition. The decals are in mint condition. It appears to never have been used, as there are no scratches or wear marks. Measures 9.5in long and sits on blue felt in its original blue box.
