Used On-Trak Model Products No.5200 J.I. Case Steam Tractor Kit - O Scale w/Box.

This is a previously owned On-Trak Model Products No.5200 J.I. Case Steam Tractor O scale kit.
The box was opened before, but the kit was never assembled.
Kit comes in the original box with the assembly instructions.
All of the parts seem to be there as they are stapled in their packets, but we do not know for sure.
