@komet163b - I got a good start on your parts. The tank base is all painted and the main base is primed. I also cleaned up the tank too, I'm actually surprised how well the tank came out to be honest.
Hopefully
@Paula is having luck with the lower
spherical elbow treads. If so, then off the tank goes to her for the lower pipe hole for the same fix.I am not sure if I have enough red paint for the base, as I used to much paint practicing on the donor's parts. But I did need that practice. If you look at the strap base and then back a few threads you can see the difference with the non-strap base. The strap tank has holes for the straps and then it doesn't have that long divot. So not interchangeable. I also put in the photos the inner and outer straps. They kind of cleaned up...
