@Daswulfthat is exactly what i'm worried about. Thanks for the help!
@ThomasPowers, I believe you're correct. This anvil is located in Santa Fe, NM so proximity wise it very well could be from Mexico. I have a ball bearing ready to go with me in my truck at all times for just such a test.
I'll need to consider this carefully, not sure if it's worth risking what I know to be a great anvil for essentially an ASO.
Thank you for your time and info!
