Afternoon Bob,
Looks like your doing a great job on a trailer slated for the scrap heap !
I found an old Snoco trailer a few years back that I bought cheap and fixed up. It had tandem axles but was smaller than your unit. I needed a smaller trailer to transport my 42 & 49 Farmalls. One of the axles was bent so I had to straighten that out, and I had a couple of leaf springs that were broken. I changed out the wheel bearings and put bearing buddies on each wheel for greasing purposes. The fenders needed to be straightened out and I painted the whole thing. This trailer was a tilt model, a little disconcerting driving up and then have the whole bed drop down

but I got used to it.
