I have an HO, lightly weathered 70-ton, single bay Airslide hopper available for sale. I bought this and some others from a fellow frisco.org member (but, sorry, I can't remember who!) a few years ago. These were built by GATC in 1968, in the series SLSF 81557-81576. I'll be glad to supply a car diagram if desired. The car has Kadee couplers, 70-ton roller bearing trucks with 33" Kadee wheels, and Cal-Scale air hoses. There is one slight flaw - the previous owner must have broken off the side stirrups on one side and replaced them, but they are different than the originals on the other side. I never did anything about it, an easy fix if desired using Tichy, Detail Associates, etc stirrup steps. See the pics. Yours for $9.75, plus I'll split the shipping with the buyer (~$3 for each of us via Priority Mail). I do not have the kit box, but will ship it in a box inside the Priority Mail box. Payment by personal check from a frisco.org member, or by PayPal using the "friend" option - I don't want to pay PayPal's fees between frisco.org friends. I'm just looking for a good home for SLSF 81564. Let me know via a PM to meteor910, and we'll set things up from there. Thanks. Ken
