Trouble with 4 speed shifter

Well I just installed my shifter linkage, and I feel that something is clearly wrong with my shifter, I take it maybe its too old (came with the car when I bought it, the car sat for 13+ years before I took it home).

Anyways it doesnt feel smooth, and I cannot for the life of me figure out how to put it into reverse, if it can even go into reverse. Sometimes it just like freezes up and I got to mess with it to get it to go back into neutral.

I attached some photos.

it says
US PATENTS
3216274 3306126

I could not find any numbers on the shifting levers.

Let me know if im doing something wrong, or if it needs a new shifter.

Also what kind of shifter is this? I believe sometime if hurst knock off maybe?

is a rebuild a better option or getting another one?
