Very Nice Chris,
Having worked as a photographer all my life it's good to see a collection of Nikon equipment all in one place.
I'll have to come over to your place and help you play with them
Over the last 30 years, people would ask me "Why pay all that money for Nikons, won't the other (cheaper) cameras do as well?
Apart from the optical quality, it's the mechanical quality that sets them apart.
I have two Nikkormat Bodies that would have had appprox 10 million shots each over this time and they have never let me down.
No other camera could hold a candle to them.
