This is a cast replica of a AM-7067/A pilot oxygen mask amplifier. It is used on U.S Navy MBU-14 series oxygen masks. This is the older style round corner amp that was used in the 1980's. It would be the correct style for a Topgun display.. Amplifier, orange rubber spacer and screws are included as shown. Oxygen mask and helmet is not included. I also have the newer square corner anps available. This item is for display only. Condition is "New". Shipped with USPS Priority Mail inside the U.S.. USPS International shipping is also available. Please ask any questions. Thank you.
