U(backwards)S Fuse

[CarlS]

Hello,

A friend of mine asked if I knew where the US (with backwards "S") Bormann fuses were made.  I didn't know but thought I'd ask this knowledgeable group.  In addition are there any with a normal US; i.e. no backwards "S"?  Thirdly, was the backwards "S" on purpose or was it a die mistake that they went ahead and used?

We haven't had a Bormann discussion in a short while so thought I'd start another.

Carl,
  I don't know where they were cast but I believe it was a casting error.
The pattern maker  knows that an S must be cut backwards so he does so .
Looking at the mold face of the metal mold the the S is now correct.
However when the lead is poured into the metal mold the S comes out backward.
I believe the WNY fuses were correct with the S facing properly.
Regards,
John

From the "Compilation," II, E, Dave The Plumber discussed the issue. Maybe he could add to the discussion?

You also see the backwards S on other pieces of Union equipment from time to time.
