Prototype 8 - Concentric rings in vermeil

Here is one that is incomplete.  Only the vermeil cap could be located.  It has an interesting design of circles around the cap and running down its length.  It almost appears like an unfinished crosshatch grid, missing the longitudinal parallel lines.  The difference, however, is in the very wide spacing, nearly four or five times the width as compared with the standard crosshatch grid pattern.
