Identify Kitchen faucet and suggest repair

[Stanstar]

Hello,

My kitchen faucet with a pull-out hose is designed to switch between spray and stream with a twisting motion. It is now stuck between spray and stream. No labels at the bottom of the faucet under the sink either. Does anybody know who makes this? Pictures attached.

Maybe Pfister? Probably generic... Post a pic of the cartridge and under the sink connections.
