Thanks everyone. After doing a bit more research and before many of you pointed out, the numbers are weight designation. Pictures are going to be a bit tough, don't like or own cell phone, consider them a major intrusion in my tranquility and leading cause for the accelerated downfall of the country I grew up in. But that is another matter for another forum. Maybe when grandkids come visit I can get one of them to snap a couple of pics and post them. Until then, not going to happen.
I have been using the anvil for small work, mostly the horn, for shaping. Was just curious as to repairs and if repairs would potentially ruin any antique value. No real intent to sell. Anvil was found by our middle son, Travis W. Nixon in his soph. year of high school. Travis went on to join the Army, Became a Ranger, won the Silver Star, Bronze Star, and Purple Heart before His death in Afghanistan with the 82nd Airborne in 2005. I still remember looking up and watching him walking across the open field carrying the anvil. He might have weighed all of a 150 lbs.
Did notice a couple more hairline cracks on one small bit of the remaining top face near the heel, but the rest of it rings like a bell when you hit it.
