This is a used and unboxed item in excellent condition.Please pay attention to the photos,as they formpart of the description. the piece is 4 inches long and approx.4.25 high/It is just under 2.5 inches deep. Beautifully crafted in brass and appears to be fully functional in terms of moving parts etc.I am not an expert on sextants,so cannot vouch for accuracy of use.i suspect that this is a modern reproduction,possibly Indian,and is NOT a vintage or antique piece. A great little collectible at a fair price
