The wooden slats for the crew seat were made by Randy Smith and Coleman Gusler.

The seat is constructed on top of a storage box that fits to the bottom deck of the 251.

The red support rail under the seat can be turned under thereby lowering the seat so that the storage box lid can be raised.

Randy tries out the seat.

Spare machine gun barrel holder and mount.

Both are fitted together before being mounted in the halftrack.
