I have had another look at the photo and it does look like the fingers are all linked together with a thin continuous strip of copper along the bottom edge. I will have to pull the graduated label of mine to check. This would make butting two strips together to make a longer length tricky as you would need to retain this electrical connection across the joint. Better obviously not to try and butt together and to make as one length. Etching a long PCB would be difficult due to need for long light box, long artworks and etching tank etc.
