[Milsurplus] Navy Model BP IFF?

[Jim Whartenby]

Have this RF to IF Converter, appears to be late WW2 vintage and is unused.  
Type CFN-46ADT uses a 2C40 1st RF, 2C40 2nd RF, 2C40 mixer, all in silver plated cavities and a 955 local oscillator.  Uses UHF type connectors, not Type-N.
What little I found on the internet shows a conversion to 432 so I assume it is in the 500 mc operating area.  Anyone know more?Jim
I wonder why people argue over the 10% of their differences and ignore the 90% they agree on?
