Beretta Air Cocking Marui?

This item was found during a clean-out of my parents' warehouse.

Before listing it, I disassembled, cleaned, and reassembled it, so it's in relatively good condition, in my subjective opinion.

When I took it apart, based on its structure, I believe it's a Tokyo Marui product, but I'm not certain as I don't have detailed information. I also don't know if it's for 10-year-olds or 18-year-olds. It feels like it might be for 18-year-olds in terms of power.

The barrel is made of aluminum.

I have confirmed that it fires BBs. I don't think there are any particular operational issues, but there's a part inside the main body that seems to be the pathway for BBs to be fed, and I'm not sure if its stopper is missing or broken, as all the BBs fall out when the magazine is removed.

I am listing several other items, so I am willing to offer a discount for combined purchases.
1000 yen off for purchasing 2 items together.
3000 yen off for purchasing 3 items together.
6000 yen off for purchasing all 4 items.
Thank you for your consideration.
