My historical documents search found a copy of the 1906, “Catalogue – Optical, Physical, Astrophysical and Astronomical Instruments – John A. Brashear CO., LTD. – Allegheny, Pennsylvania, U.S.A.”. If you would like to see the entire 56 pages, it can be found on Google Books as a (pdf) file. It’s interesting to check the cost of good optics in that era, actually not a lot more than fine instruments cost today when you take into account inflation of the currency.
If you like to read old telescope catalogs like I do then here are a few pages for your reading pleasure. (Click to Enlarge)
