With round actuators I'd say those are 4 way joysticks. Whether or not any of it works is hard to say. I'm sure most of it will work. It depends on how much work you want to put into it and whether or not you want leaf switch buttons. To make the leafs work you'll probably have to clean them and adjust them. New buttons are only a few dollars a peice so its kind of up to you. New joysticks are under $10.
No idea what panel it is, we'd probably need more info but I'd guess the same as the post above and say its a conversion.
