2 columns of A-Y on 90s machine
90s? Serve Serve Machine, off eBay. Inside, down the middle, between the 2 columns where the stock goes, is a pair of columns, lettered A going down to Y. Each one has a tiny marker left and right which can be adjusted up or down. Any idea what these are? This machine is purely mechanical, not powered at all.
