Desert Eagle .50 AE 10-inch Barrel Limited Edition

Desert Eagle .50AE Airsoft Gun Tokyo Marui Limited Edition Japan
Manufacturer: Tokyo Marui
Type: Gas Blowback Gun
Model: Handgun
Color: Black
This is a limited edition item from the Spring 1996 Shizuoka Hobby Show.
The box is damaged and the main unit shows signs of use. The E-ring in the red-lined area of the 4th image was missing, so I have installed one. I will include one spare E-ring just in case.
BB bullets will also be included.
I have not been able to confirm operation as I do not have gas. I would like to sell this to someone who is 18 years or older and can perform maintenance themselves.
