The call is a 12 hole, pre turkey in the pines (1940's) with walnut base and lid with mahogany sides.
However this one does have 13 holes, which was probably a mistake. Mr. Lynch threw nothing away and most likely just used the lid any way. Since Mr. Lynch kept everything there can be slight differences in calls made pre 1958. This explains the lid. Some calls did have valve stems and they were placed under the lid by the tuning screw.
Thank you all for the comments.
