Nope - from the 2007 datasheet:
View attachment 409759
In case it makes any difference, the cassette here look like from the 80's maybe 90's. Also, those are different SKUs, the 15-ft preloaded cassette as 70mm long roll. The paragraphe above says in 2007 the 400TX existed in that format, so I understand the 320TX were not.
Anywho, they are loaded now, but I can take a picture later once I unload them after shooting. Also once developed, I will be able to see what it was! lol.
As a side note, am I the only one romanticizing the 70mm cassettes? That format is so much better than the 35mm ones!
