Obtaining Archived Regs/Laws
Start with a request to DFW and/or F&G commission. My guess is, staff should have no problem supplying this information if it is available. They may, however, ask you to submit a public records act request to either the respective public information of legal division. The reason for doing this isn't a bureaucratic hurdle, but a formal way to help them document activities.
If this is unsuccessful, try using the California State Library. Staff there are very helpful and are a tremendous resource. I know they archive past California state statutes, but I'm not certain about regulations.
