Yeah, my bad. Paper ones were always cilindrical, you could see the layers from the sides. It was fun unrolling them, that's about all they were good for :P

They did make rectangular paper capacitors as shown at the first post here for M1 and M2:

My ESI impedance bridge uses mica capacitors are shown for M4 at the above link with the colored dots for the oscillator and filter.
