Slawek, I just LOOOOVE catalogues (note the CORRECT spelling, none of this US pretend spelling!) There is only one thing better than reading some wonderful book like Holtzapffel, or Bion, and that is a good catalogue, paper or electronic. Paper is probably better, because I can read them in bed. The range of stuff in somewhat peripheral (to me at least) catalogues is amazing.
For example, for 10 years I was doing research in Antarctica. Now I only have a minor collaboration with colleagues. One of the things that always frustrated us was knowing how deep a lake was under up to 3 m of permanent ice. The only was to find out was to drill a hole (laborious) and drop down a rock on the end of a string. One of our lakes was 180 m! A year ago, I was browsing a catalogue of hunting and fishing gear, and there I found a depth sounder designed to work thru ice! For ice fisher people I guess. Cheap, about $100 if memory serves. Don't know if it would handle 3m of ice, but there may be industrial rather than domestic units. Back to sextants. Years ago I bought a British bubble sextant in lovely condition, except the bubble was u/s. At the time, some airlines still had them, so I took it to Qantas, and the chief instrument engineer went into rhapsodies, and they completely overhauled it and recalibrated it (with certificate) free (as an exercise for advanced apprentices). Sad thing is that it has lost the bubble again. One day I will send it to Celestaire. I also bought 2 box sextants from a surplus store for $30 the pair. Both sealed in cosmolene. I got one open and had it calibrated. NICE TOYS!! The sad thing is to see sextants being sold as interior decorating items. This always strikes me as a rather degrading fate for a wonderful instrument that represents so much development of navigation, astronomy and instrument making. Oh well. These days, GPS are so cheap that it is not even worth buying the plastic Davis sextants. Ain't technology wonderful! In the five antarctic cruises I did in the last few years as a tourist guide, I didn't see a single sextant on the Russian icebreakers. Just a bank of GPSs, and most of us guides had them as well. I suppose that sextants are not even taught in naval academys anymore. Gone the way of slide rules (I still have both mine, plus my grandfather's) and log tables. For a long time, I subscribes to Christies auction catalogues for instruments. WOW! Lovely stuff, but the personal budget couldn't afford it. I was just dreaming. But nice dreams. I know that I will never have the skills to emulate the old workshops, but it is great fun turning good metal into swarf! Keep the economy growing, get catalogues, drool, and get out the old plastic! Your government needs a strong economy!
