From 1970 onwards they had it, so rather the majority.
In case you want to learn more about the details of Hasselblad, there are a couple of informative websites, Ken Rockwell, Hasselblad Historical etc. They contain a lot of interesting and useful information.
Label every loaded film back with a painter's tape label OR buy a plastic 120 box end holder and attach it to the back OR buy the dark slide box with the 120 box end holder and attach it to the Hasselblad film back. I do the last one.
Sometimes when I wash my hands, I can't use them for a while. dark slide box => optional film back hold attachment that holds a slot for the dark slide and has a opening to hold the film box tab.
I put masking tape on my Hasselblad backs and write the film name and EI (exposure index) with a 'live' roll....when the roll is done I take the tape off and thus I know the back is empty
e.g. Portra 800
I use a Brother p-touch label printer. Tape comes in several colors and a few widths. Print small medium or large type with several borders or none.
You can print any additional info you might want and even operating instructions...the sky's the limit.
Or you could do what I do. Just shoot one kind of film at the same ISO. When I do stray from that strategy, I put a piece of back artist’s tape on the camera with the ISO written on it with a silver Sharpie.
