Thin ridge board

This is from approximately a 1950s house. I don’t see anything horribly wrong with this for a 1950s house but I appreciate any opinions.

Thank you all.

There is no requirement for a ridge board. Looks like its survived the test of time.

And, as a side note, if one is going to use a ridge board, a 1" minimum board would be required, I believe.

It’s fine, Dan. No requirements for ridge boards when that home was built.

Excellent. Thank you all.

Well, there is nothing wrong with the ridge board pictured - but it is a requirement that the ridge board width be equal to or greater than the width of the cut end of the rafter. The purpose is to transfer the load from one rafter to the other (there is no bearing on the ridge itself)

Looks fine from here.
