About this document

Instructions & specifications from the factory for the 1937 WLDR model. This document specifies very interesting points such as taper ground cylinder bores & factory reliefs on stock cylinders which are always wrongly described in book publications as having appeared around 1939/1940 with Tom Sifton and his research. This two page document is thought to have originally been in "blue print" format, which would explain the dark background on these copy scans. Thanks to Bruce Linsday for sending us copies of these documents.
