Vintage 1930s’Zipper Skill’ Antique Coin-Op Trade Stimulator Pinball Working
Vintage “Zipper Skill” Coin-Operated Trade Stimulator / Countertop Pinball – Original, Fully Functional Offering a genuine antique coin-operated countertop trade stimulator, model Zipper Skill. Key features and originality highlights: Early, low-value scoring style: Playfield uses a simpler 100/300/500 point structure with a single center 1000 point pocket, rather than the escalated multi-tier scoring (jackpot values in the thousands) seen on later trade stimulators from this category. This is consistent with an earlier production era, before scoring values were inflated industry-wide. Manufacturers labeled skill games this way to distinguish them legally from payout gambling devices, a common and important practice in the trade stimulator category during the 1930s. This detail is consistent with, and helps support, the early production dating of this piece Original cabinet paint: Green top and case finish shows honest, consistent age-appropriate oxidation and wear, with single-layer paint loss down to bare wood in worn areas (no repaint layers detected). Serial number 1411 stamped into the interior cabinet finish. Factory-style pencil marking “544” visible on interior plywood, consistent with period assembly/batch tracking marks. Fully functional mechanism – coin/ball release tested and working correctly. Intact gumball vendor drawer and knob – this component is frequently missing on surviving examples of this game. (Fortress brand) key included Small pieces of period tape securing an interior wire ball-guide track, doesn’t affect play.
