, pressing based on the "pinprick" at the end of the runout string (often hard to detect without bright light and magnification). This version has the following in the rim text at 6 o'clock: (R) "COLUMBIA" (LP) MARCAS REG. [Walking Eye logo] T.M. MADE IN U.S.A.". For the very similar Bridgeport pressing with slightly different rim text, e.g., no "T.M." in the rim text, use.
