Slide rules HOME page COLLECTION 10" RULES U.S.A.
Make Pickett, USA
Model N500ES Dual base log-log
Notes

1. This rule is one of the range in "Eye-saver yellow" promoted by Pickett as being less tiring to use.
2. The rule is one of a pair with a 5" rule (N300 ES). Whilst the aim would have been to use familiarity with one rule to facilitate use of the other, in fact there are quite a few differences in the scales.
3. The rule is of all metal construction.
