For those who want an aftermarket gauge with the AC name, here is an aftermarket 30/30 sweep Ammeter gauge. This gauge is a 30/30 sweep gauge so it's not an OEM replacement for the early Tractors that sport a 20/20 sweep gauge.  White backround with Black letters. Has Allis-Chalmers name with stainless bezel. Nice looking gauge. OEM Ammeter gauges for the early produced Tractors where Black with a 20/20 sweep
