Where was a ham in Dallas who wrote extensively about 6146's, paint 
formulas, etc.  He is now a SK.  I'm sure someone on this list will 
remember his name.  Hopefully his web site is still up. He had Sherman 
Williams mixing formulas for most colors of ham gear,  Also there is an 
almost exact match for the for the original Johnson burgundy at auto 
parts stores in touch-up colors. I used it on a Pacemaker I restored 
years ago.  Sorry but I don't remember the number.  My 84 year mind 
doesn't remember a lot of things.
