Polygonal telescope
This telescope has a slightly tapering decagonal mahogany barrel and a single brass draw tube. The brass fittings include a sliding objective and eyepiece lens covers, although both are now stuck. There is no mechanical stop for the draw tube, so it is free to pull right out of the barrel.
