(1929 - 2004), renowned Dutch collector, author, and creator of Herman's Archive, a collection of 5,000 slide rule images on CD. |
• RR = Rare - 1 of 25 collectors has one; it may take a year to find an example in the marketplace. |
• RRR = Very Rare - only a few known to collectors; may be several years before it comes up for sale. |
• RRRR = Extremely Rare - a museum piece; unlikely that an example will come up for sale.
