Messko Porsche 356 T5B 1960-61 Red Dot Tire Pressure Gauge from Tool Kit
I am not an expert in Messko tire pressure gauges, but this guy is! Based on the specifications, it appears this is a 1960-61 version with Metric and Imperial scale. I have tested the pressure gauge and it works fine. I believe the pictures are accurate for the condition. The worst issues are the poor case condition and some bleeding on the dial face.
