There's no fresnel in my speedgraphic. It's a 1912 top handle speedgraphic before it was named as such really, at least on the camera itself.

By the way, this is an ancient topic to bring up. I did manage to take it apart and then discovered it was mostly being held together by decades of gunk seeping out of the leather (yuck) and the screw holes were totally stripped, no clue how it was holding itself together... Ordered a new groundglass but it's not done yet (no problem) and need to buy new tiny screws but should be doing that tomorrow, otherwise it's being held together with a bit of masking tape which strangely works It'll all come together eventually.
