Any properly mounted stereo slide pair can serve as a focusing slide.
To set the vertical and horizontal adjustments you only need to look
at the frames of the mount.  To focus the lenses you need some image.
If your slides are all in one type of mount then you need to have the
test slide in that mount.  If they are in different mounts (RBT, Albion,
etc.) then focusing will need to change from mount to mount.

Many clubs use a PSA logo or a club logo as a test slide.  The Detroit
club uses Reel-3d's alignment gauge, mounted in aluminum and glass.
