[RFI] toroid color codes

[n4zr@contesting.com (Pete Smith)]

I'm looking to pick up an assortment of HF toroids at Dayton.  Does anyone 
know how reliable the standard color codes are for unbranded stuff like I'm 
apt to find there?  I found a table on this reflector (thanks, N3EOY) from 
the ARRL Handbook, but note that the numbers of some of the more common 
materials, such as #73, are missing.  Does this reflect a renumbering, or 
something manufacturer specific, or...?

73, Pete N4ZR
