Do you need a deer call? Have you wanted the extinguisher deer call? Well, here is one that works very similar. 

There is one major difference. No O-rings are required. There is a groove for an o-ring where the drone reed part mates with the mouth piece. Though, it isnt' needed. I added it just in case you want a better seal. I felt no air leaks without the o-ring. 

Gluing - Glue the “T” shape part perpendicular to the backside of the slide. 

The REED- DIY: Find a soda bottle, cut out a section and make sure it's flat. (Use an iron on a low setting and cover with a cloth, then heat on a flat surface if it's not flat) Use the reed guide in the model to cut out the proper shape and length. 

Purchase a REED for $1:  $1 + ($5.25 with shipping 🙄) (https://illusionsystems.com/products/reed-kit-extinguisher-deer-call?srsltid=AfmBOopVumr8GzHsWtj0mREVLHtKMznGNWkxdarBUV-1u2beSSLqJlnE)
