I received a lot of tension rods. In them there were a number of Vintage Ludwig and Sonor rods. But one particular set eludes me. Many of the rods, whether they are Rogers, or Ludwig, etc, have a dimple at the base if the head. This particular one does not. It is flat on all four sides from top to bottom.
I have scoured ebay and a few other places, but can't seem to get a bead on where these may have come from.
Anyone?
