I'm hoping somebody out there can help me with info / specs about my scope. It was made by Davro Optical Systems in the USA and is clearly labelled M/N 100 QF and S/N 008C. I've tried contacting them by phone (invalid number) and email (no response).
Their current line-up of surveillance lenses

doesn't seem to have anything similar. This ebay listing
http://www.ebay.com.au/itm/281120675...84.m1438.l2649
is the only vaguely similar product I could find.
However my scope has a 90deg flip-mirror to a 1.25 eyepiece or straight through to a c-mount fitting. It also has a flip-into axis "barlow" for more magnification.
What I'd really like to know is the type of optical setup (concave front glass/primary and secondary mirrors), clear aperture (100mm, I guess), focal length/s, (or magnification of "flip-down" optics) and type/s of reflective coatings. Image circle size would also be good although it covers micro-4/3 nicely.
Thanks in advance for any info or ideas about how I might find out more.
