Many thanks Ken61 for following along and brainstorming w/ me & once again, a whale of a good postulate. But I'm just not sure and the sand has just been pouring in my hole in the Lindner-Daly sandbox & I haven't sorted it out just yet. I too think 1877 to be that transition period but just how many lower scear A & D Body Action might Schoverling, Daly & Gales have peddled from 1877(1875) to 1882??? Now the upper hanging & lower intercepting scear variants cannot predate 1882. Again, still a lot of sand to sift but aren't we having fun.

Cheers,

Raimey
