A wonderful piece of electronic history, it comes with its original wood case and instruction booklet. It hasn't been tested and is sold as a collectible only. The original 3 mm leads/probes are missing.

The instrument was designed to take an EverReady U10 battery, which is now obsolete, and is not included. 

The meter is in good cosmetic condition with some surface scuffs and blemishes. The outer transit case is made from black paper covered wood and has numerous scuffs and blemishes where the paper has rubbed off.
