Brown Board with Silver Fingers

Hey everyone, I was taking apart and old tape player this week and pulled out these boards. They look like low grade with silver fingers. Has anyone ever seen anything like this before?

Yes, I got some similar to those from an old engine analyzer. I didn't find any good prices on them.

Grant, those fingers are tinned, not silver. Pull any TA caps and toss in your low grade box.

The relay in third picture may have silver contact points

Also give a quick look at the lil black transistors, some may have gold legs. (example)
