thickness of 3155 versus 3135 movement?

[timelord]

I have been going crazy to find any data on the day/date mechanism 3155 mvt?

I only found data on that the height or thickness of the earlier 3035 mvt between 6.15mm and 6.3mmm and that of the even earlier 1556 mvt to be 7.03mm.

Cannot find anything on the 3155 dimensions. Does anyone have any data on this? I believe it is a little thicker than the non day 3135 movement which I believe is 6.0mm

Also the height of the mvt would begin at the base of the movement plate and not from the hands pivot. Is this correct??

Thanks for any input
