Measures approximately 30 cm long with a 17cm diameter plate and a 14cm x 3.5cm handle that is constructed of steel and brass components. Attached is a small plate that is engraved with a serial number, model number, manufacturer name and date, and naval inspection markings. When not in use, the computer can be suspended by the chain and hook attached. Shows typical surface age and use and is still in operating condition. A very nice example.
