Linda,the holster shown with the model 27 is a model 814-it first appears in a catalog dated 1941.The black holster with the hammer protector-carved model 614 in the 1950's catalog cut-first appears in an early post-war catalog that is undated but is,I believe,from the late 1940's.Neither model appears in any of the 1930's catalogs I have.
Regards,
John Witty
