How do I find my PII Week and Plant?

I've got 3 PII processors I can get a hold of for free and I'm trying to deterimine their OC'ing ability. Being new to Intel CPUs, I'm not sure how to find the Week and Plant location of the processor. Here are the Processors:

PII 350Mhz -
B80523P350512E sl2wz
19080214-0423

PII 400Mhz -
sl357
19390123-0016

PII 400Mhz -
sl357
99200305-0013

I love google
