Serial No. rubber stamp strip
Serial Number Ink Stamp for 1950/60's Gibson Vintage style font.
Hard to find...exact Vintage size 3/16" = 4,7mm, the closest Type font for Vintage Gibson Guitar Restoration or Updates... Compare the hundreds [if not thousands] of black ink stamp numbers from the 50/60s. They vary, usually based on how the ink sits on the stamp, but also how imperfectly the stamp is pressed to the headstock. That can lead to numbers being misread, even by experts.
