1968-69 340, 383 and 440 4-Barrel unsilenced except early 1968 models. Mopar Performance reproduced these in black wrinkle (P4529001) and chrome (P4529002 or P4529025) but factory units were always black wrinkle.

I think its just a repro chrome one. Im not positive though. That site has some good info on air cleaners.
