I was going to perp a blank to turn a Wall Street II click. I was seeing what blank would go best with the finish of kit by holding the nib assy.next to theblank. I set the brass tube along with the other parts on my lathe stand. I heard the brass tube hit the floor. I stepped back to see were it went. I did find it under my shoe, flat as a pancake or should I say crape. I guess I should have left the parts in the bin I use to store them. I can order replacement tubes from Woodcraft so it no big loss.
