Larry,
I hope this gets to you after so long since you posted your Regulus Two question. I myself have been trying to get Regulus information on the first Regulus. In doing so I searched the Fine Scale Modeler web for Regulus information and found your posting.
There is quite a lot of information on the Regulus Two on the web. If you go to google and type in Regulus it will take you to a host of sites that cover the Reg Two.
I find it quite interesting that your favorite saying is the motto of the USS Tunny SSG282 the first Regulus submarine to launch a missile. I myself am a militery retiree of 31 years with the first part of my career in the Navy on the Regulus One project. I had an opportunity to ride the Tunny while I was stationed at the Submarine Base Pearl Harbor.
If you get this let me know and as I search for my information I will pass along to you anything I see on the Reg Two. My address is RSaddlemire @sc.rr.com.
Regards,
Richard
