I edited my own question after the fact. In the TiP history, it looks like in 1976, they went from TIP Transport Pool to TiP Inc. Believe it or not, these old mudflaps still have flexibility to them. haha
wash/scrub them well, then use a brush with red and white enamel paint on the logo and then tire "dressing" after a couple weeks curing time.
So, did some work on the old trailer today. I stand corrected! The "bars" along both edges are actually hinges. Rusted solid so thats why I thought they were solid. So, I'm thinking it is an old, raise sides type of trailer. There is no interruption on the stringers and they are a consistent 12" apart so I don't think it had a hopper originally. As far as progress, I have all the old electrical removed. Next question? Should I rid the trailer of the copper brake lines and go to 1/2" poly or is the copper a more reliable system? I'm not a fan of how they ran the lines originally. They are on top of the stringers and prone to damage when there is no boards to hold them in place. Any thoughts on that?
look along the frame rails below the cross-members(stringers) for welds. That will be where the hoppers attached if used. 12 inch spacing is standard for convertibles with metal floors or hoppers. The spacing helps support the plywood walls when down. If you are going to haul nothing but lumber and hay type commodities then plywood floors over 12 inch cross-members will be adequate and will save weight. there were hay haulers in the 70's and 80's that just had tarp material under the cross-members to catch falling debris. I would re-plumb your air system and hang your lines under the cross-members and against one frame. Poly lines will be cheaper and should work just as well. Consider putting maxi-brake chambers on and changing the valves at the tank to control them. If your brake chambers are solid and pins and bushings are in good shape then piggyback maxi-pots are a simple way to go.
I used to deliver to Anchor equipment early 70s but don't remember much about them. The LTL that I worked for had Brown trailers we hauled LTL out of Southgate Ca to Salt Lake City. Lots of steel out EM Jorgensen to the EIMCO plants usually with Dart paper cups over the top to cube it out. Then would load grain back to California in them. There was a headboard and the sides and roof bows would be stored in the nose along with a tarp.The side boards were all aluminum with D rings in them. The doors usually left on the rear and had a slot just inside to put a piece of plywood across the back. Their were 2 straps on each panel to tighten down to trailer and the hooks on trailer for bungie cords. Good Luck..
My 26’ 1950 Fruehauf-Carter still has the copper lines and cast iron glad hands. I pull it everyday. You ain’t gonna get 73 years out of poly. My ‘51 Diamond T still has all the copper. That old copper is much more thicker wall than you get today.
That's part of my dilemma with the brake lines as they are now. It's guaranteed these copper lines will last but the way they ran them, I'm not too impressed with. The emergency line runs along the left side of the trailer and the service line runs on the right side of the trailer, and this really wouldn't bother me BUT they are run on the top of the stringers and are not fastened at all. They were originally to held in place with the decking under edge plates. Since I'm not doing decking right away, this leaves the airlines in a vulnerable spot to get damaged. My thinking also says this would make any kind of line servicing a nightmare because the decking would have to be pulled up to reach both of the airlines and the electrical. Yes, it was run there also. If it wasn't for the placement of the copper, I would probably keep it.
