Stanley Prescision Level w/ Original box

A precision level is a measuring instrument, used together with a measuring staff, to gauge the exact differences between the levels of two or more positions on the ground. The level has two main parts: the tribrach and the telescope. The tribrach has 3 foot screws which can be rotated to allow the telescope to give the required horizontal line-of-sight. The tribrach also has a vertical axis, around which the telescope may be rotated to sight the measuring staff. On the telescope is a level so that accuracy in leveling will be possible. The telescope may be tilted gently (up and down) by turning a "tilting screw" which is located between the telescope and the base. This tilting screw helps level the telescope before each staff reading. This engineer’s level has a 30 cm (12") telescope with internal auxiliary lens to permit focusing without changing the overall length and preserving the balance of the telescope. The level is signed on its side Stanley London Made in England. The original wood box also is also signed in the lid WF Stanley & Co LTD. 286 high Holborn London WC1. The level and box are heavy; therefore special shipping rates apply to this item
