Teebodk, forget super glue! Even the gel! It will not hold!
......... all though there is an adhesive. It is called = "LAST GLUE" because it is theoretically the last glue you will need to buy. Attaches anything and everything. LAST GLUE advertisement guarantee states 2 years. I do not know how good it really is although I have seen demonstrations, and the results are favorably impressive. The end result looks a bit messy probably for the demonstration, but I am sure that some filing, sanding, or whatever it takes for display could clean it up. The real down side is, you need their "cleaner product", their "filler product", and finally the the glue. ALL 3 ITEMS ARE REQUIRED! On the internet, the prices are extreme for a fix you are contemplating. In fact they are extreme for just about anything that I would need to repair. You need all three items to make it work. And you do not get that much!
Without real close-up in-focus pictures, hard to tell if fractured or just plain cut apart. My money would be on just plain cut. It is different and maybe you can find a set of trolly wheels to supplement the trailer.
Even if Jim welds it, without some strengthening across the entire chassis both bed and cab, welds are strong, stronger than the rest of the casting and THAT is where a fracture will occur = next to the weld.
The FODEN FRACTURE is similar to the BEDFORD fracture, referring to Jim's Post welding the fractured Bedfordcab and chassis. There is not as much stress at the cab base as across the entire chassis. Additionally, since the bottom rails are missing and the box bed front locating prongs are also missing, these locate the bed into the chassis casting using only the rear spare tire(tyre) screw.
You can try to return it to original, lotsa work and could be done...........
ME?
KEEP IT as is. It is VERY UNIQUE.
If just cut to make a code 3, a real shame that some one would cut up a good toy. Like you have said, their priced out of this world, even broken (fractured).
Good luck with it. A nice find.
Go shopping..............
