WTB: GGD B&O Slumber Coach & K-Line NP Cars

I am searching for one or more Golden Gate Depot Baltimore & Ohio Slumber Coaches, 3 rail. I would be thrilled with one, but two would be even better. 

Willing to pay a premium of $50, above the original $249 list price for cars in new / like new condition.  If you bought one on close-out in Dec of 16’ this is a 33% mark-up, what other trains these days resell at 1/3 above original price? 

Also in search of the 2 add-on cars for the K-line Northern Pacific North Coast Limited in 21”, new or like new condition. 

My email is in my profile.

 Thanks,

Jason
