@Edraven99 Here's how I attached the cone/balance pipe with the nut. I think this is what you meant in your email, right?

Looks like you may have been in the same boat I'm in with my grenade... Makes me feel better about taking off the beige paint...
I was looking mine over though and If I use some paint thinner and elbow grease, it looks like it may come out as just silver steel, no petina... So it got me wondering, what would it's original state be? Would it have been just "silver" steel?
If not, were they blued? painted?
Any ideas?
Should be just steel under there. EL, the grenade you have looks like it was covered in cosmoline to prevent rusting, and was later painted over top of that. That is what created the lumps and bubbles in the pain. If you thinner and then the wire brush, it will bring it down to just bare shiny steel just line Roman said. Mine was the same way once I was able to clean up all the dried up cosmoline.
Thanks for the bump in this thread. I love revisiting these things.
