@RailRide I just put all mine on the track; a few less than what you listed.
The Standard O trucks put those cars kinda high up in the air 
Here's my lil' collection of AHM: The boxes when new had a tear-off panel over the clear window. Some of my acquisitions still have that panel intact, so I elected to leave it in place. Some of these boxes (like the UP gondola) are slated for repairs with cloth tape and PVA glue like that used on books, to make them a little sturdier, and I'll either re-glue or replace the windows with clear acetate. I also made up a styrofoam insert to straighten the warped cardboard of the more worn boxes, so I can gently moisten them with a clothes steamer. Hopefully they should hold their corrected shape once dry.
(The PFE dupe is thanks to being a little quick on the Ebay trigger--I didn't check to see if I had that one since the very-good-condition box had my attention. I'll have to own up to that one 
)
At least one of these cars were fitted with Atlas O couplers (which won't grab a 'claw') and perhaps one other was fitted with Kadees. My plan is to retrofit all of these with the AHM conversion couplers shown below. They give you the equvalent of the 1970's Atlas couplers, which aside from being non-operating, will mate with typical 3-rail couplers.
