French Curve or Irregular Curve

Description
This flat wooden drawing instrument has curves on the outside and within an inner opening. There are numerous scratch marks and stains. A faint pencil mark reads: #30E (/) 40 ¢.
The shape of the curve is similar to an instrument shown in a Reeves & Sons catalog from 1904.
