Since I was there in the 80's, I ordered the same shields he used. It is indeed the same as what Medela has now. They were made by "Cannon". I also had the original Haberman feeder. It was a wonderful tool then and still is today.

Subject: type of nipple shield used in the milk transfer studies
Rachel,
Yes, the studies on milk transfer with nipple shields are old. The Woolridge study compared an old mexican hat, thick rubber one with a new thinner shield, unclear if as thin as the current silicone shields. The other 2 studies were done with a thin silicone shield.
