Larry,
The 7000 - 9049 were built by General American Car in 1922-23 using new bodies and rebuilt trucks.
The Wabash Oct.1943 equipment book shows 48 car equipped with racks for frame loading.
Another group of gons with the same dimensions were built about the same time
10000 - 10124 built by the Wabash shop in Decatur, IL in 1923-24-25, also using new bodies and rebuilt trucks.
10125 - 10524 built by Streator Car Co. in 1925 using new bodies and rebuilt trucks.
Truck used on the cars were Andrews and Bettendorf.
When the Wabash started building the 13500 - 14849 41'-6" IL steel gons in 1944, they began scrapping the
above gons and by Dec. 1949 they were all gone.
