300 400 sickle bar

Can anyone tell from these pics, is this a sickle for 300 400 series??

Doesnt look like it. Most of the Habans look very similar, but that looks nothing like the 300/400 bar I have here.

Not for the 3-4-series,

Thanks guys. Belongs to a customer who is trying to mount it to a B 110.

Just trying to figure out what it is..
