Dear Dan,
George Kohs brought these models in about the 2005 -2008 I believe.
About the same time Lionel came out with there JLC GG1 in 3 rail.
Very surprising that the models look identical with the exception of the pans.
I have a total of 19 GG1's ,the 6 JLC G's were 2 railed for me by Joe F.
When I place it next to my Kohs version , most people think the JLC is a Kohs !!!
BTW- I did not pay any anywhere close to that price for my Kohs GG1
The only difference between men and boys is the price of our toys !!!
