Sight on SB2C Helldiver

[gorizont]

Please, can anyone answer, what sight was installed on Helldiver and had it computing unit for calculation of corrections or it was simple reflector sight as on late Dauntless mods ?

I found that the sight was common reflector Mk.8. More interesting that it was coupled with Mk.30 director. But I don't know if the director was computing unit and if it led the sight automatically.
