Sandblasted and glue-chip are the earliest types; I think by 1915, the pressed types were also being made; I have seen a old catalog online IIRC of pressed glass from the 30's. If you have a good eye it should be apparent which ones are too Art Deco, which you would want to steer clear of.

If you wind up having to buy new glass, Rockler makes a few pressed types that might be stylistically appropriate, like this one, called 'Rain':

Oh, PS, in my craftsman bungalow the bathroom window is stained glass with a very simple block pattern, if that helps. Your best luck might be to scour salvage places and eBay to find one that fits.

Thanks for the tips! We could definitely go the salvage approach, but figured since we're replacing the windows anyway, might as well go to double-paned glass in them. (There are three rotting windows, all on the same side of the house, because they get a lot of exposure to the elements there---hoping the new windows will help on that front with tighter fits, too.) I like the rain pattern, though, and also a hammered glass I'd seen---just can't tell if they really look appropriate or will stick out like a sore thumb. (We'll probably keep a curtain there anyway, but want the option of getting rid of that at some point, since the bathroom gets awesome natural light if only it weren't for the neighbors' window!) I'm actually curious as to what the original glass was---clearly what's there now was replaced at some point, and the house that looks in predates our house by a decade, so they clearly knew about the issue when they designed it. Hmm....

I saw some window film at Benjamin Moore which you put on with water. I used some years ago that I had to order from the UK, it worked really well.

There are a ton of window films out there if you want a quick and easy way of fixing the problem. They're generally not very hard to install either. Might be a good choice of an interim fix while you find the appropriate glass.

Most home centers have a basic "frost" pattern for under $20.
