K-Line Golden State Streamliners

I have a set of K-Line Golden State Streamliners up for sale. Each car is in excellent to near mint condition and have a total of about 3 hours on the track. They all include all diaphragms, silhouette inserts, and 4 still have their extra light bulbs taped inside on the Styrofoam.  There are two original outer boxes included. I don't know if there is a difference between the black and silver boxed coaches and the red and black silver coaches but the cars look  identical. I am asking $ 135.00 OBO including shipping anywhere in the continental U.S.  I will ship the very next day if bought Monday thru Friday. I insure everything that I mail at no cost to you. If interested please contact me with your best offer at k.richardson4@hotmail.com.
