Although the first quadrant faders from Painton had studs for each position, the later type had a silver plated pcb with 'fingers'. Actually, the photo you posted at the top of this thread is the pcb type.
Even later Painton's were just carbon track 10K audio taper types.
The earlier types - as used on the REDD desks - were physically wider than the one you posted a pic of and also didn't have the clear perspex escutcheon but a black plate that was screwed on. On photo's of the desks, you'll see that every five steps (except the last one of -65dB which happens after 4 positions, off being the next position) there is a dB of attenuation marking: 0, -5, -10, -15, -25, -40, -65 and off
