S&S bunk cars

After looking at the photos of the two bunk cars at the S&S I have come to the conclusion that they are 04951 and 04953. Both of these are in the pictorial on pages 161 and 162. They both are truckless in 1967 and where photographed at Monarch. The car in the foreground is fairly obvious as you can read the number although I thought it was 04451 at first. The one in the background is more difficult but the window and door spacing looks right. It also has the roof walk that shows up on 04953 in the pictorial. Wish I could see the grab irons on the right side to search for the really bent one on the bottom.
