I had a nice Canteen that was a little scratched up and had some decal loss. The hatch or lid was intact and worked well but the hitch was broken off right at the spread rivet and that caused the base to fall away when you picked up the model. The rectangular hole in the base (that fit over the spread rivet) was missing the thin outboard edge. I needed to replace the missing metal with some JB Weld epoxy. The first pic shows the rough build up of epoxy.
The next image shows the base after the epoxy has been filed and shaped to restore the thin missing metal at the front (where it sits over the spread rivet).
Now that the base will sit level on the body, I needed a hitch. The Canteen hitch is delicate and has a shoe that allows the model to sit nearly level on its own. I dug two models out of my scrap bin and used them to construct a realistic looking hitch for the Canteen. The top half of the hitch came from a scrap 23d base. the photos show how I cut it away and what the piece I used looked like.
Before removing the hitch tounge, I tapered the edges to look more like the hitch on the Canteen. I used epoxy to glue the base onto the spread rivet. The hitch tounge would nest against the epoxy repair of the base and against the lower edge of the body (two points of contact). Next, I needed the lower half of the hitch and it needed to have that "shoe" to allow the Canteen to sit level. I chose the use the lower half of the hitch tounge on a bent up/beat up 9d Boat Trailer. The part was already removed and fixed to the Canteen before I took pics, but here's the trailer showing the part I removed:
Here is how the two different hitch tounges look when put together (along with a finished pic of the Canteen).
It's not a perfect match for the original tow hitch, but it works very well and takes a model from the junk box and puts it back on the display shelf.
