Tokyo Marui P-90 TR with Silencer

This is a P-90 with a custom silencer attached.
Purchased new 7-8 years ago.
Never used in actual combat, only fired 3-4 times with BBs loaded.
It has been stored in a closet for a long time, so there may be some dirt. Please check the images. (I will clean it as much as possible.)
The original P-90 box is available, so it will be shipped in the box.
Includes the original P-90 magazine.
Battery is also included.
The dot sight's battery is dead, but it should work if you replace it.
Only the silencer has some damage to the internal sound-dampening urethane, so the sound-dampening effect may be reduced.
Fully functional.

I understand the price is set high, so I am very open to negotiation.
