Hi I have purchased a 1927 Buick Master Six sport tourer. I'm new to the classic car environment so please bear w me if I'm asking a stupid question. I am looking for gauges that work - but it is not clear to me what is original - I have a round speedometer and from pictures I've been able to find on the net I haven't seen other Buicks of that time w round speedometers so seems like it is not original but would be great if I could be pointed to where I might find out. I've seen pictures w dashes/gauges that have amps/oil/water temp/gasoline level that does look original at least from comparing to what I found on the net. The gauge which contains amps/oil/water temp and gas level is not in good shape and at least the gas level and water temp don't seem to function .... and I'm wondering if it is possible to obtain a replacement somewhere or if they can be repaired/renovated. I'm attaching a photo that shows what my dash looks like. thanks much
