Hey Darrell, the top two look like my gauges. The faces look like brushed stainless. The amp gauge COULD be a service replacement, maybe??? I don't think they are reproductions in any case. Those wouldn't have Made in USA on them. I'm sure there will be others posting to confirm. I often wondered if there was more then one supplier myself.
Good point. Another thing to note is that the color of the needles are different. Fuel gauge needle was painted before being peened were as the amp need was painted after.
