I recently bought a Spen trailer off of Craigslist. The Spen is a civilian copy of the M-416 with a tailgate and ball-type hitch. It was built in the late 1940's and sat in a barnyard for a long time since then and needs some restoration. I cut the welds that held the tailgate hinge and straightened the bar. I plan to cut the rusted out bottom of the tailgate and weld in a pipe. I cut the round fenders off and will add flat top fenders. The front corners need to be patched and then the whole thing will get sandblasted and painted. I think I'll keep the axle and hubs after I clean and repack them.
