Keep in mind it is acceptable to simply leave the bridge specified generally (ie through truss) if it is not apparent in the photos. While I agree the panels are narrow suggesting a possible Whipple. I cannot see the diagonal members in the photo provided.

Judging by the panel length (eyeballing the picture) and build date and length, this was probably a Whipple. I wanted others input before editing the truss type.
