Description:

Transit is housed inside wooden storage box. Resting on a small tripod brass base are a series of tiers containing a adjustable and non adjustable metal components. Two tiers from the bottom up lead to a round compass face covered in glass with measurements scales surrounding it with adjustable dials and two ‘levels’ filled with clear liquid. Resting up on the compass tier upon two pairs of triangular legs is a pivoting telescope. The entire instrument rotates upon a central ball bearing on top of the metal base tier which rests upon the wooden base. On the external edge of the compass tier is a scale from 0 to 360 which remains fixed while compass and pivoting telescope rotate. Telescope has two objectives and a cover (one objective and the cover are stored separately in the box). Attached to the pivoting telescope above is a level and adjacent is a wheel marked in four quadrants, from 0 to 90 in each.
