Not sure they still exist...the release comes with the part you glue into the bomb...the mechanism goes on the pylon so as long as those are for the right scale and the pylon formers are cut to mount the mechanism you are golden.
So, in otherwords, you find a release for the scale of your plane, have someone help you draw up the former shape to make the pylon so it will accept the release.
kinda like making a servo pocket fit a partucular servo.
