I don't remember these boxes being marketed as an aviation box but could be wrong--they were a sold as a heavy duty roll cab/ work bench---and they were built strong! I bought a used '80 model (old emblem) KR562A in '85 when I got an inside job, no more road service,and still use it in a truck shop. Mine came with the tow package which I don't see on this box. Recently on the local CL a seller had one on for 5 weeks --don't know if it got sold or not--for $1200 but he had a top box also. Another seller had one with a side box and looked clean for $1500 ---just depends where you live. There was a member recently who did a restore on one---can't seem to find it. BTW, the brake really comes in handy!
