After 350 I smile and try and think back as to how many had the rib running around the center of the harp and how may were just smooth. Releasticly this was a cast part and how long did the mold last between each casting? Did the rib eventually dissapear or did the next mold not have a rib on it?

I believe the outside should be as original, no polished harp, no grinding away marks that were there when the meter was new, again original.

Each of us who restore these meters puts their own imput into the restoration, restoring them the way they want to, do what you want, you are the one who will look at it.

If you have any question about the meter, call me at: 314-427-3943.
