You might want to check a local medical supply store for the fetoscope. Dunno how open to the public they tend to be, though. AllHeart.com
has one for $20. You might want to post to the midwives subforum & ask for brand recommendations.
The vit. K was a bit harder to find, but Birth With Love.com midwifery supplies
seems to have it. It's a bit of a confusing product description, but the exact source seems to be a substance called K-Quinone, so you can check your local herbalist for it perhaps.
