The picture is a bit fuzzy but that ring thaT says top on it looks more like a second ring to me. No bevel almost always means a second ring. But, there are strange things and this may be one of them. Who made the rings?
I was trying to show the bevel. It has the bevel on the inside lower edge. I have no idea who the manufacturer is. I'm sure it came in a low buck rebuild kit. It came with the box of parts with the engine I purchased.
