This small bit of Boy Scout equipment is meant to provide aid in getting through the woods and reading maps. The round compass is 2" across, mounted on a hard plastic ruler 2"x 3". The compass was made in Sweden, the tracker was assembled in the USA. This has measurements and directional information to aid in using a map to traverse a territory. In one corner is :"Silva System", and the Boy Scouts of America National Council emblem is in another corner. This bit of history is still useful, and would be fun for a troop to use. I will combine orders for discount and shipping savings. Please email me with any questions you may have and thank-you for shopping here at Something Wonderful.
