I Picked this pen up and can't find any backround information about it. The clip says "Keystone" and has a K inside of a keystone symbol. The nib says "Carter". The nib is in rough shape and the ink sac is shot, but the body is in decent shape. Any help is greatly appreciated.

The pen is Wearever. K in a circle is for Kahn (David Kahn).
The Carter nib does not belong but it does not matter.
The black and cream color is interesting - I am not sure if this is the one but in some of these cheap pens the pattern was ... painted

Thanks for the reply. I'll look up Wearever and see what I can find.
