I found it! You were right svHyLyte, it was a Taylor Made ladder. And you were right too, Therapy, I had taken it out of the Lazarette last year without giving it much thought. I don't know what I thought it was, but I definitely wasn't thinking ladder.
Well I still need to get some new scrumper buttons, as the old ones are rusted out. Otherwise it looks to be in good shape. Thanks, all!
