Definitely stock shocks with Ohlins stickers. That's one way to get a cheap upgrade.The adjuster rings look exactly like those on the OEM sachs, as does the whole top section, and the overall finish, even the way the variable rate spring get's tighter at the base.
If they are Ohlins, then he wasted his money as the Sachs appear to be just as well built - LOL.
I've gone from being 90% to 99% sure they are Sachs with decals. Don't trust anything else he says, unless he has receipts from Ohlins.
