Technical
Data - Dimensions : 94 x 65 x 20 - Weight: 190 g - Double inclination scale: 0-110% (positive and negative) - Distance scale: 1:50.000 = 8 km  NIEDERMANN's Patent no. 199512: Fig. 1 on page 3 |
| ARTILLERY LEVEL (made by E. F. BÜCHI Bern) in French: SITOMÈTRE (Click on the pictures for enlarged views)  FUNCTION: Depressing the push-button located close to the leather strap releases the compass card and causes the metallic blade (visible from above, picture in the middle) to swing back. |
 (Function - cont'd) This blade is a mirror reflecting the image of a small tube level (see next item below). It gives thus free vision onto a portion of the compass card (3200 mils) through a prism and onto two portions of rulers graduated from right to left from 0 to 8 (upper row) and from 24 to 32 mils (lower row). |
