Prototype National NC-303 Receiver?
NC-303 in an NC-300 Chassis

Don K1JQ sent me info on his recently acquired NC-303 for my NC-300 & NC-303 serial number database.
I was confused because it was an NC-300 serial number (481-1927) but looked like an NC-303.
This is a REALLY INTERESTING receiver!

It is hard to believe that it is just some ham's conversion - there are too many changes and that just doesn't make sense.
So perhaps it is an NC-303 engineering prototype that was built on an NC-300 chassis?

Some things I have noticed -
