Full Description:
These are solid brass reproductions of a Dumpy Level, also known as an Engineer's Transit.  A dumpy level is an optical instrument used in surveying to transfer, measure, or set horizontal levels.  The level instrument is set up on a tripod and then accurately set to a leveled condition using the spirit level and leveling screws.  The operator looks through the eyepiece of the telescope while an assistant holds a tape measure or graduated staff vertical at the point under measurement. The instrument and staff are used to gather and/or transfer elevations.  Measurement generally starts from a benchmark with known height determined by a previous survey, or an arbitrary point with an assumed height.  Azimuth readings are taken using the internal magnetic compass.  These Dumpy Levels are fully functional, but are not certified accurate for surveying.  These are very beautiful and unique instruments that will add distinction to any desk or office.  A beautiful solid hardwood box is included for storing or displaying either Dumpy Level as well.

The Large Brass Dumpy Level stands 4 3/4 inches (12.1 cm) tall, 6 inches (15.2 cm) long, and weighs a very solid 3 pounds 3.6 ounces (1.46 kg).  The Dumpy Level has a 5-power inverting telescope and a focusing adjustment.  The telescope has a removable brass lens cap to protect the large 1.5 inch (38 mm) diameter objective lens.  On the left side of the telescope, there is an adjustable spirit level with a protective cover.  The underside of the cover has a mirror to aid in reading the spirit level.  The base has three leveling adjustments and is threaded for a 1 1/8 inch diameter surveyor's tripod mount.  The azimuth angle can be precisely adjusted using a fine tuning control.  There is an internal magnetic compass for azimuth angles.

The Small Brass Dumpy Level stands 3 5/8 inches (9.2 cm) tall, 4 3/8 inches (11.1 cm) long, and weighs 1 pound, 9.6 ounces (726 grams).  The Small Dumpy Level has a sharp 3 power inverting telescope with focusing adjustment.  The telescope has a removable brass lens cap to protect the objective lens.  The base has three leveling adjustments and is threaded for a 13/16 inch surveyor's tripod mount.  The azimuth angle can be adjusted using a fine tuning control.  There is a see-through magnetic compass on the right side on the Dumpy Level.  On the opposite side there is an adjustable spirit level with a protective cover marked "Stanley London."  The underside of the cover has a mirror to aid in reading the spirit level.
