Crown BCK #OH98  NPK 3 Car Box Car Set including NKPHTS Convention Car for 2009. This is a Limited Edition run of these box cars.  Made by Buffalo Creek Graphics.  They are known for very limited-edition rolling stock.  Detail is terrific.  This set includes the NKPHTS Convention Car #29073.  Only 23 were made.  The other road numbers (#24558, and  #29000) only had 50 to100 total pieces produced never to be made again.  The Convention Car has special printing on End Tack Board.  See pic.  These are beautiful.  Graphics are crisp.  Great way to add to your box car rolling stock.  Spring loaded diecast trucks and wheels.   Mint condition.  These are not MTH or Lionel but are definitely as nice or better.  I ship via USPS and FedEx.
