Here is a late war rig. 44 dated filter and a Schm-1 from no earlier than 1944(snout details). This is my rig that led to my question in an earlier thread regarding the grey filiters. The snout hardware on this mask is grey as well and it has six factory applied patches on it. The decon container is not original to the mask, only a gift from the person I bought the rig from.
