Russel, I grew up in Goldthwaite, TX and have seen literally tons of old plow points and parts that did appeared to be galvanized. This appearance comes from the lime and alkalines in the ground. You can take a new plow disc and leave it on the ground for a couple of years and it will have this same look to it. You would think it was much older also. Everything in your photos are safe, no galvanize. Good score and very wise of you to leave the galv. stuff. If there was any pipe in the material you left it was most likely galv. also alot of old farms had windmills that the tower was made from galv. angle iron. But if it was old farm equipment you should be safe from the galv. Sorry for the length of this post.
