If anyone has one that is original can you post a picture? Thanks Attachments 7AAC9AA0-470D-49A5-8FD6-5CE17C4AF8CC.jpeg (134.27 KB, 158 downloads) 1948 1.5 ton grain truck with pto driven dump bed.

Also having that black and white picture of the layout is nice. I’m glad I didn’t straighten mine out. Lol. Thanks again 1948 1.5 ton grain truck with pto driven dump bed.

I'm sure someone will come along with good advice. Good luck to ya. 1948 1.5 ton grain truck with pto driven dump bed.
