[Boatanchors] National XCU-50 crystal calibrator

[Michael Raskin]

National XCU-50 crystal calibrator.  I have two of them but have no way to 
test as I don't have an HRO receiver.  Both have the tube and tube shield.
1)  Case very clean - looks almost new - $75
2)  Case dirty with mild rust but no dents - $50
Shipping extra.
