Wow my thread revived from the dead.
I am planning a big clean this Friday, as I have been really busy the past two weekends.
It is definitely an H...I can see it real well in person. Who knows, maybe it was already replaced once.
Another interesting thing you guys may know about. It came with 2 extra different hose couplings for connecting the propane. The original tank is still working and I saw it fired up before I bought it, but the guy also showed me two other couplings that he had...they were a different diameter. I had never seen anyone say this before, so I thought I would bring it up.
