Just wondering about the piece in the center's unusual dome design just above the wire groove. Sandwiched between two other Hemi pieces for comparison.

This design seems a bit scarce. I have looked through the Pic Poster and there might be one or two others like it. Both of those were in colors such as yellow and cobalt blue. Looking on E-place I have found none with this shaped design.

Interested to know the scarcity of this.
