bottom studs indicate system (logo on top studs), which brick is correct?
I have some of these bricks, the only one without stud logo is the one with the small triangular supports.
Even the ones with the low cross have stud logos.

Judging by the BL photos all of the ones with bottom tube should have logos on studs (do we differentiate between old and new logo btw?).
I think there's a version without any supports and a big logo at the bottom center too. That likely didn't have stud logos.
@N. W. Perry:
Jumbo bricks definitely are not Mursten. Wrong scale and wrong era.
Kiddicraft bricks also shouldn't be compatible with Mursten afaik. Using inch as base unit vs mm. Also technically a "third party" item, so anyways not Mursten.
Regarding the difference Mursten <-> Automatic Binding Bricks:
I think the main difference is the presence of a molded "LEGO" text inside of Mursten (which came later). Which is something I am not sure if it should be included in the LDraw model anyways.
I couldn't find much info on the topic, hard to tell if this is due to lack of general interest or indeed a lack of differences.
If the bricks are basically identical, there wouldn't be 2 files, so I guess putting the few possible Automatic Binding Bricks in the Mursten category is fine. Keep in mind that the "Homemaker" label isn't always that historically accurate too (just as an example).
