Japanese paratrooper bayonet on ebay

[SVW1945]

Ebay # 330202383521.
Questions. I haven't seen a lot of these espeicially in mint condition. Is this a real one. It has the right maker marks and length? Can somebody shed some light on this?

7 3/4" blade, maker mark and overall appearance add up...I'm leaning toward original but you may want other opinions...if everyone is not watching it

it's original be prepared to spend 2500.00
