The shoreline shape is the part that every time when I see it, I want it to be different.

the seat lug is interesting where the ears are not the same top and bottom- that is ok.

actually I do not knock the plug and play aspect- not part of the program to make it a go.
when Mario was involved he was able to get the lugs cast with a thinner wall- do not know how that was achieved as the casting houses want a thicker wall, less scrap castings.
