Unknown Air Box - help?

anyone know what this air box goes to?







there's no markings on it of any kind. i feel like it may go to some old Honda, but it came with some KZ650 parts i got all at once. i have some other random stuff that doesn't go to my bike as well.

any ideas?

With the angle of the inlet tubes it may have been a V twin? :blink:

it looks like the one i had on my 84 vt700c. (honda shadow)
