Vintage Sheaffer Lifetime Flat Top White Dot Estate

Description

I really don't know much about these pens and pencils I will be selling.  Feel free to tell me if I am off on my information.
This is a nice Sheaffer pen from my moms collection. It measures 4.54 inches long. Nib is very nice. Pen looks very nice. Some brassing on ball of clip, and ring.  Needs a new sack.  Still a nice pen!
Please ask any questions before buying.
