Eye Wash Baths

We have just started collecting eye baths, and we are looking for referrences for books on this subject, or an address where we can find information.

Any ideas?

Paul, are these the same as eye cups? If so, I'm not familiar with a sourcebook on them. Several of the general price guides do have a few 'value listings' for them under Medical Antiques.

If you come across a glass Nasal Douche, please let me know. My daughter had one, and I broke it when it fell out of the box.
