Lowes has a similar one that is very reasonable. Replace it :)
Get a magnifier and look close for any logo or emblem.
Slinky???
Kraus-Boldin maybe?
Does it look like one of these?
Is there only one opening in the ledge at the back of the sink for plumbing? How do you change the water temperature?
You live at McDonald’s?
There should be a weight attached to the hose under the sink.
I found the manufacture name on that weight when I was having faucet problems.
There was no name on the faucet, only the weight.
Maybe a commercial unit?
Look at pre-rinse sprayers. Although none of these seem to be a color match.

I agree with whoever said it would probably be cheaper to replace than fix.
Here you go, but in brushed nickle:
Fapully Contemporary Spring Single Handle Kitchen Sink Faucet with Pull Down Sprayer, Brushed Nickel
Otherwise looks like a perfect match. And surprisingly cheap.
It has GREAT water pressure with no modifications.
Almost too much pressure.
The fan spray ABSOLUTLELY knocks all food off the plate before the dishwasher. No pre-wash needed in the sink. Highly recommend! bought from amazon too. https://www.amazon.com/CLOFY-Kitchen-Sink-Faucet-Sprayer/dp/B075JFYS14/ref=sr_1_sc_2?s=hi&ie=UTF8&qid=1530233938&sr=1-2-spell&keywords=clofy+kitche+faucet Best wishes https://www.amazon.com/CLOFY-Kitchen-kitchen-faucets-sprayer/dp/B075JGPV6C/ref=sr_1_sc_3?s=hi&ie=UTF8&qid=1530233938&sr=1-3-spell&keywords=clofy+kitche+faucet Great faucet for the price!

Try replacementparts.com. But we just had a faucet repaired, the plumber said he’d never seen one like it, but I looked up the brand on line at Delta, and even though it was discontinued, they still have the parts for it. Which is good, because it has a built in water filter, and I didn’t want to part with it.

This one looks real similar for $50 new on ebay: https://www.ebay.com/p/Oil-Rubbed-Bronze-Kitchen-Faucet-Pull-Duwn-Sprayer-Sink-Deck-Mount-Mixer-Tap1/20003873073?iid=263052366252&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D44040%26meid%3D45c4b9f1896a49faa6b824ab11e16250%26pid%3D100005%26rk%3D5%26rkt%3D12%26mehot%3Dag%26sd%3D182524200695%26itm%3D263052366252&_trksid=p2047675.c100005.m1851
The service call alone for the plumber would have paid for a super deluxe, full wiz-bang, high tech, brushed stainless steel, WIFI capable water faucet.
AND it will connect to SIRI, ALEXIA.
The problem with faucets is that a $50 knockoff can look just at good in a photo as a $500 one. The insides are what sets them apart.
