This is a collectible World War II era R.C. Pickett pocket slide rule. It has a leather Carrying case and is approximately 6 inches long. One thing to note about the slide rule is it appears to be in very good condition and hasn't had heavy use. However, I'm selling it mainly as a collectible because the inner slide portion is stuck in place. It likely needs to be taken apart and freed up, but I have left it as found.

Overall, this is a Nice combination of unique pocket slide rule and very well made leather pocket protector. Please check the photos closely for additional details.
