How can I recognize the model of a keyboardio?

I’m searching for some information about the model of one keyboardio. I know the serial number, but I can’t distinguish if it’s a MP2 or a MP3 model. How can I do?
The keyboardio is a S/N: 003546 (it’s a model 01-Q)

The model is 01-q. It’s a quiet click one. Is there a reason you care specifically about which production run it was from? They’re pretty much going to all be the same.

At that serial number yours was most likely in MP6+ I believe.
