Microsoft Wiress Mouse 1000

Hello! So the other day i lost the receiver (dongle) for my Microsoft mouse 1000 from about 2012 i think. I really like this mouse and i don't want to bin it just because i lost the receiver, so if there is any way to replace the receiver and to re pair the receiver to the mouse please tell me. One other thing that is not so bad is that i lost the back plate for the mouse. I'm not so bothered about that but it would be nice to have it back again. Thank you!
