Wanted Crank arms just like these. Don’t know what brand they are

Looking for some crank arms just like these in the borrowed photos.
They look like Adventure Components but the reliefs are completely cut out.

I would say AC too, perhaps specially machined. Get your file out.

I'm selling some FSA Afterburner cranks at the minute check them out, you'd be very lucky to find a set of these knocking about these days..
