Identifying Kingsley Ballpoint

[Gkatona3]

I am trying to identify a pen that was given to me as a gift. It is 4 1/2" long, stocky, with a matte emerald green barrel and black lacquer top and bottom. There is a decorative silver band at each end of the green barrel. There is an additional silver band above the top patterned back with is engraved with "Kingsley" with a crown above the "G". I found this picture online; it looks exactly like mine, except mine is matte green.

 

I would like to know the model/style, when it was introduced, how much it cost, etc. Thanks in advance for any help.
