Mosquito fighter-bomber tactics question

Hi,

I've gone through countless web pages and come up with nothing on
this subject, so I hope someone on r.a.m could clarify things a bit.

This regards the bombing tactics used by Mosquito FB.xx variants
in World War II. Since the FBs could only use the rear bomb bay (due
to the 20mm cannon) and the bomb aimer's position was taken up
by the .303 calibre MGs, how did these fighter-bombers actually
aim their internal bombs?

The wing-mounted bombs were probably simple to aim using whatever
gunsight was used for the cannons and MGs, but what about the bombs
in the bay? Since there was no bomb aimer, did they simply glide-
bomb their targets using Kentucky windage and the gunsight, or
was there a way of "guesstimating" the release point from level
flight, like a normal laydown attack?

Thanks in advance.

Cheers,
-Stegu
