Gauge #3 looks to be an 914-6 gauge.
Gauge #3 is a fabrication.
It appears as if someone started with an early fuel gauge (part no. 914 641 102 10) and changed out the handbrake light insert at the top with a 914/6 type temp gauge insert, as well as replacing the little indicator lenses with modern versions. Original 914 & 914/6 combo gauges are pictured and described here:
