primitive corn sheller

Here's an early primitive that I got at auction this week. At first, I was puzzled as to what it was. It was with a lot of other primitive farm items, so my thoughts led to what might this farm tool be used for. Looking down the length of the wood, it was dished out to guide something toward the arrow shaped projection. Hmm... I know, it's a corn sheller.
I tried it out and it shells the corn easily, even if the husk is still on the cob. It directs the kernels directly into the bucket via the holes under the arrow shaped projection.
It works absolutely great. It's amazing how early homesteaders & farmers thought of ways to make their chores easier.
It probably was made by a local blacksmith, or maybe even the farmer himself.
Well anyway, ... it goes into my corn collectables with the other shellers
P.S. I forgot to mention its size..... it's 26" long X 4" wide and is about 3" thick
