Judging by the nose plug I assume the FFM has no mouthpiece. That combined with the pendulum mechanism must have been a huge CO2 headache producer. Does it come with analgesic tabs?
You are right on one point here - I used the CDBA / DSSCCD for about 5 years, in the early to mid 80s- CO2 headaches were a common occurence, depending on the level of exertion produced during the dive. The long shallow swims in oxygen rebreather mode were quite often the producers of "head pain".
