folks,

i would like to know as close as possible the date this plow was manufactured.  it had been sitting for 50 years when i found it, and have plowed with it last 2 years, at plow day at my place in central texas. it doesn't cover much ground, but plows great.  all parts on it are coded dp which i assume represents disc plow.  by what little paint was left on it, i cleaned it up best i could and painted it as you will see in attached pic. thanks for any help anyone can give me.
