primitive vintage grain sacks w/ patching and mending, seamless type heavy cotton feed bags

Lot of four vintage grain bags, all heavy cotton, seamless sacks. Only one of these is marked Bemis, but they're all of the same general type and weight, and all measure about 40" long x 18" wide.

They all have some stains or discoloration though the fabric is thick yet. These have had lots of wear over the years, and have have ragged holes and charming very primitive patches - tons of character on these old things.
