Impress them with your zipper Savvy and tell them you believe it to
be a #5 coil Zipper.

I am not sure on the size but it is a Coil.
Most Upholstery shops worth a crap will have a bin of goofy junk
zippers and pulls.
But it is close to a #5.
Brand of pull will not matter. Must be coil and not tooth to work.
If you purchase 10,000 Pulls from my supplier I can put your name on
the pull if you feel like it.

Not sure if that helps or makes you cross your eyes.
but to replace the zipper take the seam loose on the lower corner
where it is sewn to stop the pull. feed it back on then use a small
amount of Latex type adhesive to glue the flap back over the end of the zipper.

Have fun!
