You don't have a practice chanter there. You have to have one to learn to play. Get one. What one? There are lots of choices but McCallum, Gibson, Naill, Hardie are a few. Get a wooden one if you can or a plastic one. Find a local band or instructor. The benefit of a band is you get peers to work with and instruction - at least to some degree - for free. I have a local band and the pipe major teaches me.

Get some corks. Pull out the wooden bits where they plug in. Do not untie the base parts. Put corks in the holes and blow it up with the blow stick. Put some pressure on it and see if it is leaking. Yes? See a person who can work on them. No? Great. You have the first part and it is in fine condition. Then find where the drone reeds plug in to the base of the drone stocks. plug them in and blow from that end. The tapered end with the thread is what plugs in. If they make a low, bleating sound then they might be good. If no sound then see a person who can work on them.

There are instructional videos on Youtube that can be helpful. There are books with the fingering. If you can learn the scale on the practice chanter and can get the drones to sound then there is hope.

If the bag is good and the drones are good then you might find a real chanter and reed for relatively cheap. Again - consult with that person who can work on them. If it is a leather bag and not a hybrid and if it is in good condition and the reeds work then you might have a pretty good setup for a workable set of pipes. Don't lose heart. Enjoy.
