It's a Dunn and Co, which I understand was made by Monhagen Saw Works near here in upstate NY. Looked like a standard dovetail saw at first. Spine has been smacked down onto the plate creating a slope that, from what I understand, is not correct and often done in ignorance. It's also been filed with a decent amount of rake and some fleam but not quite as much as I would expect in a dedicated crosscut saw. Here's the odd part that I'm unsure about, though--upon closer inspection I noticed this:

I've never seen a backsaw with breasting before but the rest of the teeth are jointed pretty well which makes me reluctant to think that this curve at the toe is unintentional.
Another odd detail is that the saw plate isn't square at the toe:

Anyone ever seen anything like this? Was this saw designed with these details in mind or was it likely just done haphazardly by someone a hundred years ago?
