Hand cut and rolled tin cones.  The dimensions on these are right, the hole at the top is small enough so that no crimping is necessary, just like the old ones.  What else makes these so special?  The tin was burned in a fire and then "flashed" in cold water to patina the metal and change the molecular structure so the sound is different.  These cones sound like the old one too.
