6927. Field and Marine Glass, japanned and covered with

 power about 3f times. The telescoping bar is inde- 

 pendent of the focusing screw, as described above.

The glass No. 6927 represents a happy compromise between the magnifying power 

 and the size of the field, as neither of these factors has been reduced at the expense of 

 the other. This makes it particularly well adapted for a search glass and for general use. 

 The focusing screw is independent of the telescoping arrangement, so that closing 

 the glass and drawing the tubes out will not disturb the focus to which they have been 

 adjusted by the focusing screw. 



6935. Field and Marine Glass, japanned and covered with 

 morocco, with sun shades, object glass 21 lines, 6 

 lenses, magnifying power about 3 times. Glass in 

 sole leather case with handle and shoulder strap . . each $ 12 75 



6935. Field and Marine Glass, like No. 6935, but object glass 24 

 lines .
