Model N200 ES Trig

1. A nice feature of this rule is the way the trig scales are arranged with duplicate C and D scales on the back of the rule. It's an uncluttered presentation of the scales. I rather suspect than many other manufacturers would have crammed another scale in there destroying its effective simplicity.
