      Comments about Astra Iiib Sextant - Trad Mirror:

      Not a german brass precision instrument, but more than adequate, and for the price, a very good value. Feels solidly constructed, with very tight tolerances. Just what you would expect from a precision instrument. Optics very clear and bright. The box is not of equal quality however, but can easily be replaced with a better case that this instrument deserves. Would not hesitate to recommend.
