Remote Controllers

Im aware that any DCC remote controller is compatible with any DCC player.
But I’m curious if there were specific remote controllers included with certain player models ?
I have two different remote controllers and I wonder if anyone know as to what players they originally came bundled with.

The small one on the left is for a Philips 951 or 730.
The one on the right is for any 2nd gen like a 300,600,450 etc.

That is great info.
Thank you very much.
