I love bumping 5 year old threads. I'm focusing on another area of my shop this weekend, saws. I found a Pennsylvania Saw A5, so I Googled it. And much like the Google search that originally brought me to this lovely forum, it brought me again.
I guess the OP got his answer, and never came back, so I'll pick up where he left off. So, yes, John K, my saw does have the Quaker etching on it. I've got about a half dozen saws, mostly Disston, and I've been searching out the best way to clean them up without ruining the etchings.
