Reading telescope with stand

Early scientific instruments, such as spinthariscopes and spectrascopes, were often so sensitive in their measurements that it was almost impossible for people to accurately view the miniscule readings with the naked eye, and would require microscopes or 'reading telescopes' to magnify the measurements for recording. This example was built by the West London Scientific Apparatus Company in the early 20th century, and was likely used for a galvanometer to measure small electrical currents.
