Record Bow Compass

Record Bow Compass

Usage conditions apply
The pen and needle points (including its screw) are missing from this steel instrument. Because the pen point may be removed, this instrument is not like other bow pens in the collections. A disc for adjusting the width of the instrument is on a screw between the legs. A cylindrical ridged handle is directly attached to a ring inserted into the legs. The leg that would have the pen attachment is marked: RECORD. The object was received with several other instruments in a wooden box, 1984.1071.13. Compare to 1984.1071.10.
