I tried posting a reply several times... so if this is a duplicate, I apologize. Your article is very interesting. I will be interested seeing your full stack of bars or partial collection! Thank you for your post. I learned something new about Engelhard bars!
Glad you enjoyed the article @silversaver888. It took me a long time to learn how to use these resources. As well as understand what they even are! If I can pass this info on them I am satisfied!
