Here's a very attractive WHITE DOT SHEAFFER LIFETIME oversized flattop pen in black from about 1929,  probably a model C8.  Notable flaw is the missing clip. The pen is 5-1/4" long and has a barrel diameter of .518"   The lever filler will need a new sac before it will take up ink. No brassing to the gold filled lever or cap band. The black radite is in flawless condition. There is a prominent 3 line monogram on the barrel. White Dot is located on the top of the cap.  Nib is a large serialized (#4970339)  14kt SHEAFFER LIFETIME fine width firm point.  It is straight, firm and with good iridium.  The pen also has visulated section to enable ink viewing.  The pen is still bright and lustrous and I suspect had very little use.
