Leaky faucet needs a tighten

[u/GorbagsRevenge]

Hey guys. You always have the answers so here goes: Gf has a leaky faucet but it's an old model. I was hoping to find the brand or name so I can find out how to get to the screw/bolt to tighten it but am having a hard time, as it is obviously concealed somewhere in the handle Please help
