I cant say for sure, but it is only able to fit a VC-125 or VC-160, its black (Earlier) and the only ones without indicators were the early VC-125's (1971) and the replacement catcher.
So it is either a 1971 VC-125 catcher, or the replacement catcher sold in the late 70's early 80's as a spare part for the VC-160, after production of the mower had ceased.
It could be either (More likely the latter) but they are the same, so this is what you would need to do an original 1971 VC-125.
