- Lot Description
Very, very, early and rare John Date diving helmet with hand-formed bonnet. Date was initially an importer of Augustus Siebe helmets and copied the Siebe model (1840 – 1872). This helmet has the same three light design as Siebe including Siebe’s non-adjustable exhaust in the same location of the period under the air intake elbow. In addition to Siebe’s screw-in faceplate Date manufactured helmets with a hinged face based on Sampson Barnett’s design. That style was eventually adopted by the U.S. Navy in 1916 for the Mark V helmet. Another change Date made was to have round side ports, like Heinke, not oval like Siebe. The port guards screwed to port frame externally. The early helmet manufactures often numbered the various components to be attached to helmet. On this model Date numbered the two side port guards, 1 and 2, to match the side port frames which are numbered 1 and 2. The photos show the right-side port with the number 2 port guard lining up with the number 2 port frame. The left side port is stamped number 1, but the port guard has been attached with the number 1 attached to the bottom screw hole of the port. The bonnet shell is in very good condition with expected working dents and hand-formed the castellated brazing line can be clearly seen. On the very early Date helmets the air inlet was angled to a few degrees to the left from vertical. (See Helmets of the Deep page 184. The design of this bonnet is earlier than any shown in the book.) Another feature indicating its very, very, early manufacture is that it was made prior to the introduction of a locking device. The breastplate is a hand-formed replacement of the original John Date that was lost to time. It is non-recessed like the original and is slightly irregular in its hand-formed construction. The breastplate features the early Date style of brailes with the joints at 2, 4, 8, 10 o’clock like Heinke, and not Siebe’s joints at 3, 6, 9, and 12.
