Never tried to measure the mesh size, but the pickup screen on a TR3 is only
a little coarser than window screen.

Be sure the wire can't vibrate at the edge of a solder joint.  The original
TR3 screens are very apt to crack where the mesh is soldered to the pickup
tube.  The cure is to add several loops of wire to secure the screen to the
tube, so it can't vibrate at the edge of the solder.
