Here's a walk-in that was purchased by a dealer, then resold within seconds. This is touted to be the best CD 159 F.W. Gregory known in the hobby. These were highly prone to corner chipping and surface slicing and from what I hear, none are known in vnm to mint condition...but longtime collectors claim this example is the closest. They were used on a short stretch of the CPRR in Northern California's Sierra Mountains.
