Does anyone recognize the brand and approximate year of this dual axle boat trailer? There are NO identifying marks or decals or plates or etched numbers.... It was under a 1964 Thompson of Peshtigo 20 ft. Off-Shore wooden lapstrake I/O boat
That's' a serious heavy duty rig.
The last boat I had was a Starcraft and it had a Spartan trailer with that type of bent tubing and hardware. Did have a tendancey to rust from the inside since there were no drain holes in the hollows.
Might search Spartan and see what comes up.
