TRS80 model 1 keyboard

[Pat Ridge]

Hello everyone! I’m looking for some help. I have a model 1 26-1004-1 with the hi-tek keyboard. The enter key is missing something on the right side that keeps the key level. Maybe it was a spring? I can’t find any pictures of the back of the enter key to see how it was made so I can affect a repair. Does anyone have one of these older models you could get me a pic?? Thanks!
