I have the yellow and green MEC PS-1's, nice!
There was a complete spread sheet of everything Weaver offered once on line. It would be great if Joe could post that list for everyone. It was on here years ago too. I may have it on an archived CD?
Most good cars offered on ebay are all mostly bought up. Many variations of the older style and overpriced junk has mostly been on there this past year with a couple of rare exceptions. We also have the issue of plastic trucks & couplers which I stay away from. There are many uninformed Weaver sellers unaware of all the changes Weaver made through the years. From a price point, they have no clue as to what they are selling. The later, last offerings were the best production wise. No weights in the door way as one example of several.
MTH and Lionel's latest freight car models have far surpassed Weaver and Atlas O in detail and construction in recent years.
Maybe Joey can post that Weaver car list?
