Here are a couple from a rainy At Home Airshow at Finningley many moons ago. The colour picture is from an aviation mag in the 70s and found its way into my log book. Sadly I didn't take any pictures during flying training. Just surviving the course seemed higher priority at the time.
The standard fit in my day was an API, a GPI, a drift sight, gee and console. Decca was only fitted in the Dominies IIRC.
