I had a bit of luck yesterday. You might say a small bit of luck:
I think this is a transitional style like a "Dalton-Hardaway" but perhaps a little later.
Update: The fields are in awful shape. The tractors have beaten the surface and the corn stalks are lying, shredded, on the ground. Where they have re-conditioned the fields with harrowing, there has been no rain and all the surface is dusty, the same color as the dirt. I spent all day with my son, looking at the ground in MA and RI and we found almost nothing. So let's wait for a good rain before spending more time examining dust.
