As seen in the picture, this is a remote control with jog-shuttle dial, model RMT-M20, for a Sony MDP-series player. It is the Japanese model, it should work fine for American models as well, & I will be glad to provide translations for the button text if you need them. $15 postpaid to buyers in the United States, by negotiation elsewhere. Or (see my other thread) will trade for an MDP-series lower disc clamp assembly, although if you have one of those going spare, you probably no longer have a need for this remote.
