but i would say that it is prolly not original, bc where is the silk-screening on end plates...? not seeing the left right gain or sub or whatever those pots are for... - i would say there should be some identication marks for the componats on the end plates. im not seeing them
so if i had to guess, and sadly not in my hands for personal review....but by the pics, it looks like could even be powder coated- there is chrome powder as most may know (in fact prismatic just came out with a new one which is supposed to be better nicer brighter, etc, but havent tried it yet myself)
but you see the framing edge... or what appears to be framing edge on the fins... looks like thick paint/coating to me... If real chrome and done well, those should be lil more square...but again not seeing it in person, but also isnt real chrome like more mirror like reflective.. on some angles looks like wavvy reflective look kinda
