[QUOTE="scoutshouse, post: 1410925, member: 267"]No, [USER=56]@moreotherstuff[/USER]... It is a mapping tool for measuring areas. Sperl's are for drawing circles. There are compass arms/inserts for smaller circles (that bottom element): [IMG]https://i.ebayimg.com/images/g/RBQAAOSwb59d3bL-/s-l400.jpg[/IMG] Sperl's are beam compass attachments for bigger circles: [IMG]https://i.ebayimg.com/images/g/mdoAAOSwxZxcG4p1/s-l400.jpg[/IMG] Charvoz and K&E are two brands I recall off the top of my head, but I don't know what "F" signifies. Maker and possibly age would be the things that would make them more valuable :)[/QUOTE]
