[TheForge] King's bar

[Andrew Vida]

OK, I have to make sure I didn't have too much LSD with this morning's 
coffee.

Most, if not all of us know the basics of wrought iron.  In particular 
we are familiar with single- double- and tripe-refined grades.  There 
was an even finer grade that was refined a fourth time.  As far as I 
recall, this was called "king's bar".  Am I insane?  I mean on this 
point and not in the general sense.

I remember reading about it in a book and that particular volume listed 
the various English proof marks that were employed for the various 
grades.  As I recall there was a special mark for King's Bar.

Anyone recall what book this may have been in?  What I don't recall is 
whether I bought it... I seem to think not, but why?  Po'ness, perhaps.

Thanks,
