John -

This antenna model is almost identical to one that my brother was given in
the 1970s. I see you used a torch (scorch marks)..... the corrosion can be
removed with naval jelly or an electrolysis process (described in
boatanchors newsgroup).

You should be able to wind a proper coil and have a 1/4 or 1/2 wave vertical
for 15 or 17 meters. You could use schedule 40 electrical conduit (gray
PVC) for new cover of coil.

I used a paint stripper gun to loosen the PVC. After I discovered that
It would not be difficult to replace the sleeve I lost interest in
trying to save it.

On the next trip to town I will get some naval jelly for clean up. The
bracket hardware needs it as well.

My current plan for this project is to experiment with short 80 and
160 meter verticals. This is pretty early in the project, I have not
constructed the radial system yet.

The focus will be on matching methods, I feel the EZNEC software
answers most of my other questions.

This is an academic pursuit!
