Well, I suffer not only from dislexia, but also blurred vision. It's a 4800A

The meters look the same as the 4805A though.

To my defense, my cardiologist told me last week that my "good" cholesterol was too low and he recommended that I drink a glass of red wire with dinner every day to raise it (having to say that to a Frenchman, never happened before...) I may have over done it a little...

 I read 'Vector Voltmeter' and assumed HP 8405A.

 I'm somewhat skeptical as to whether the 4805 meter is made that way.?
 It is true that the RX meter product made by Boonton Radio (not be be?
 confused with Boonton Electronics) and later bought by HP had custom?
 engraved drums.  However, these were drums, not meter movements.  The?
 meter on the RX meter is of course just a nulling indicator.?
