Sig p226 frame marked “rev 3”

has anyone seen this on a p226? I bought it used. Was doing a deep cleaning and found this marking under the grips where the hammer spring goes.

I tried to google it and found nothing.

I went to so sign up on there and ask or also. But i could not register with my email. They do not “free” email address. And i only use a google account.
