My HO scale layout yard needed 3 grain cars. I found reasonably priced ones on ebay, as I wasn’t too picky about the road name. All 3 came unassembled with their original boxes and all. Here are some thoughts that run thru one’s mind during the assembly process.
All 3 were '3-bay Covered Hopper’s, as stamped on the end of the box, but the instruction sheet indicated ‘54 ft Covered Hopper Car’. No big deal, close enough.
One was a red MKT hopper, the Athearn number on the box is 5305. According to my handy-dandy “Standard Guide to Athearn Model Trains” book (by Blaisdell and Urmston Sr), this model was manufactured by Athearn in 1971. It has existed unassembled in a box for 50 years. Brand new, someone paid a whopping $2.98 for it. I paid $10 for it on ebay, before shipping. Somebody’s return on investment wasn’t the best, but it’s better than nothing. (Around 2.44% annualized.)
The old blue box is in pristine condition. Translation - it has not been juggled around in a crate to hundreds of train shows trying to find a happy home. Upon opening the box, it reveals that it has spent most of its life in a basement. Just the right amount of musty smell - not too much and not too little. The box was stored unopen over the years - no dust whatsoever. The axles and screws have bit of rust on them. No big deal, the plastic wheelsets get replaced with IRC ones anyway.
The red body has a nice age to it. The MKT letters were probably white at the start, but now have a bit of a nice fade to them. The folded 1/2 page instruction sheet faded in a bizarre way. The side that faced down to the bottom of the box is noticeably more faded than the other side facing up. Mind you - if you needed to contact Athearn for a replacement body, it would have cost you $1.25 back then. I have assembled a number of these 54’
