pinholes in Spotmatic II shutter

I recently purchased a Spotmatic II in lovely condition. Unfortunately, my son, who knows nothing about mechanical cameras purchased it for me and I've noticed that there are three very tiny holes in the shutter curtain. I can't tell if they go all the way through the fabric. A Spotmatic SP and an SV3 I have don't have anything like this in their shutter curtains. Does anyone know if these little holes are enough to affect exposures and if they are likely to indicate a serious problem with the shutter curtain (stretching?)? The seller has generously offered to allow me to switch the camera with an SP he also has for sale, but as I've never had a Spotmatic II, I would prefer to keep it if it is still likely to be useable.

You could contact Asahi Photo or Harrow Technical to see what they would charge for replacing the shutter blinds.

Blinds with holes in are no use.
