Default Factory Mercury rocker arms or Chinese garbage?

Was considering the Crane 13760 (golds) or the Comp cams 1620 and saw these on ebay. Anyone heard of these?
https://www.ebay.com/itm/361398808774?ViewItem=&item=361398808774

Based on a quick google search the part # 8M0044735-C doesn't exist. I put nothing past the Chinese to laser etch a fake Mercury part # on them.
If these are actually the real deal and as described the price is dirt cheap.

I think you answered your own question in the title.

I'm surprised Merc lawyers aren't putting an end to that.

I always thought merc hiperformance engines used crane golds although they look just like the crane 13760's. Possible crane makes these for merc? Just a guess. I know in some cases or perhaps many the trunions and tips are made over seas and the body's here in the USA. These look like a nice rocker and if they fit like cranes they should fit well. Cranes always seem to fit great for me any way. .

They might be Scorpion Marine rocker arms for Merc. I have a set of silver Scorpions similar shape. Cost about the same.
Marine Endurance Series

Zoom in and look at the finish. Notice the pockets in the casing. I don't think Merc has anything to do with these. Second pic is from a Merc parts site.

The later merc blue motors use silver scorpion rockers. Those are knock off junk as shown in the horrible casting
