1934 build SFH in California (earthquake country). I don’t believe these metal plates are past repairs but I’d like to give the buyer good information. Does anyone recognize these size and type of plates bolted to the foundation wall? My wag is earthquake retrofit but they appeared to be pretty thin plates unlike the other retrofit plates I’ve seen.
I agree with your WAG on the earthquake retrofitting.
Here’s a similar, albeit IMO a better built bracket, that’s used for the same purpose.

Kevin beat me to it, but it does look like retrofit to me.
Simpson makes both styles.

Yeah, I’ve seen those stamped brackets. These looked pretty thin especially for not being stamped.
Edit: I looked up the FRFP and it states 8 gauge thick which is close to the thickness of mine

If you’re in CA, then you should be able to look up the permit history for the home.
If there’s a permit for a retrofit, then it’s a retrofit.
If there’s no permit, then, well, Uncle Bob did it.
A proper retrofit is symmetrical in effect, engineered, and properly installed. A bunch of thin plates can stand in for a smaller number of stronger plates.
The connection to the wood is a very important part of such a retrofit.
There is a preapproved plan set in California for quick retrofits, but that ain’t it.
Also ground to wood == termite, photo right.
