How can I get a replacement remote for my ancient tv?

My 13" Emerson TV (model # TC1316RN) works fine. A wire on the inner board broke off. I can't fix. The TV is small (sits atop the frige). With cabinets, can't fit anything big. Inside the remote, on back of the component / sensor / chip board, it reads "86 - 51", and "090-390086-51", and "280291".
Can it be replaced. I am 6' (no problem for me to reach on/off, channel and volume buttons... but wife is 5'). Help if you can. Thanks. Dave (CT)
