Help me identify old equipment trailer

[Dpgoat]

Any idea what company may have made this old gem? Just picked it up today and no nameplate. The wood deck is actually bent to fit. It has 2 dexter axles. Looks like it had a railing in the front part tha was cut off. Any idea maker or year?

Deck a little over 15’ long
