It wasn't much fun, but it's done
I was able to reuse 3 of the old tubes, but the tar filled one was just too nasty. So I fabricated one from scratch.
Luckily, I had an old gift wrapping paper tube that was exactly the same diameter.
I reused the old wax to seal them.
I applied some yellow ochre acrylic paint and created a water slide decal.
Here's the final product.
Restuffing an old tube. I made a point of using the same colored wire so the tube legend is correct.
All four are finally done! I think the rest of the set will go fast now.
