      Congrats on your fun in restoration, Milt!
       
      The maroon bug you are copying is not a Racer.  It is a Standard Radio bug from WW II.  It was a special order of the Army Air Corps, and is a very scarce key.  It came in many base finishes.  The gold lines on the Std Radio bug were always quite far in, and did not include the little filigrees of the Vibroplex bugs, a style that dated all the way back into the 1800's.
       
      On Vibroplex bugs, the distance from the edge varied widely.  I have seen them as close as a quarter inch to the edge on thin-based bugs made in NorCross, GA.  On the Stda Radio bug they were 7/8 of inch in.
       
      Most typically I think the lines were in the order of 5/8 inch in.
       
      Scratchi-dits... Some of the new rigs are very sensitive not only to trying to follow incredibly small gaps in contacts rubbing across the face of one another, but also, we have found internal keyer to lose the instruction from paddles when the contacts on the paddle simply conduct with a little resistance in the circuit, like one ohm.  We found that if we changed the Begali contacts from tungsten to gold, the "mistakes" disappeared.  You could hold the tungsten closed and watch an ohm meter flicker around, always below about 1.2 ohms, but that seemed to cause the radio's internal keyer to make mistakes.  Think what the oxidation on silver contacts on a bug would do!  A big loaded up cap seems to fix it.
