"if I have that understanding correct, maybe instead it had to do with registering the securities for sale on some exchange / going public"
The 10SB12G filing registered the shares (but not for sale on some exchange / going public)...it acts to render the company a reporting company. After acceptance by the SEC...as you can see it took several amendments to get that done...an issuer becomes an "SEC filer" and is obligated to file 10-Qs, 10-ks, etc.
"why are you asking me do all your work for you" Sorry. It won't happen again.
