I have the T with the mask. I can do 12 exposures of 6x6cm without mask, and 16 exposures of 6x4.5cm with the mask. WHen you insert the mask, it pushes a small metal rod of sorts that move the counter from 12 to 16. I also have a Rolleikin for the T, and when I use this the only thing I need do is make sure the pressure plate on the back is set to 36mmx 24mm. I do not doubt the claim that somewhere in existence is a custom T that is capable of 24 exposures, but according to Prochnow himself Ts NEVER had 220 capability. So this must have either been an error or it was a special run that was never sold.
