Hello Greg, and welcome to the best pen turning site on the web. Be sure to check out the library here for some of the best pen information available. The link is at the top of the page. If the info you need is not there, then by all means post your question, with photos if available, right here in the correct forum. Very rarely have I seen a question go without an answer for an hour or longer. For your entertainment there is one article in the library you should make your first read. That is the list of most of the acronyms you will encounter here and what they mean. Very helpful.
