I may have had your ml-l3 for a short time.
I live here in JH and stopped briefly at a pullout just south of Moose a while back. I looked down and there was one on the ground, looking like it had been driven over, but I had to try it. didn't work so I bought a new battery for it. Still didn't work. I kept the battery for a backup and the sleeve but disposed of the actual remote. Want your sleeve back?
