Old Russell Erwin Lock Found - 1898?

[CHAPP12]

So guys I haven't found a lot of coins on this old farm place but I've found a cool mixture of old iron pieces and overall buttons. I love old locks and was glad that I dug this one. I was hunting the side of where I have guessed the old home site is and got a huge signal from my atpro. I have dug so many large iron pieces from plows and even a part of an old cast iron stove top, I thought this would be something like that. Pleasantly surprised and as you can see from the pics was able to make out the maker and the patent date. I have attached an example pic of the lock (top row center) I think it is from google images.

patent date is Nov 22 98

Also, do you think electrolysis would work on this piece to help restore it.

Thanks and happy hunting
