I just bought the SP version of the new Athearn single bay Airslide hopper. This car means peanut butter sandwiches at least twice this week. It is well detailed model. I believe that the Frisco had some similar, if not identical cars, sooooooo (Bob) if you still have your contact at Athearn, I believe I have some SLSF Airslide slides I can forward to get this project underway. Please advise.
