Very generic, no logo, no brand name, it came in a plastic bag in the shipping box. Hard to get more generic than that. I tried to post pics but for some odd reason the pics were being blocked. Go figure.
At the time, it was a little cheaper than the brand name version from Hobby King as the shipping from Hong Kong cost more and Hobbypartz has free shipping still.
of course, just in case I ordered a cylinder and piston from Hobby King though. I can always get a ring from Frank Bowman. Those two parts were pretty cheap and irressistable.
