The Admiralty pattern (AP) mask is no longer available as a spare part. Although Avon were one of the prime contractor (including Dunlop) they were not the manufacturer. The polycarbonate face plate tooling was by Hopkins with the rubber tooling by MEL. The complete assembly was by Hopkins who supplied it to MoD.

The unique features of the AP mask was its panoramic view, its water filled rubber sealing skirt and the low WOB due to its good design and bite mouthpiece within the mask surround. Agreed the nose clip was a force to be reckoned with and the rubber spider was very flimsy. As MOD now required commercial off the shelf COTS products the silicone version of this mask never was completed.

You can’t get a new mask now as they are only available as complete assemblies with the rest of the diving twin set and regulator, and in a very limited quantity, as the SDDE or the CDBA closed circuit diving set. Both of which are now pretty much collectors items. Out of interest the SDDE/DCBA unit is listed in MoD list at £840.00 and the closed/semi closed 02/mix CDBA set at £8320-00 …each!!! So anyone with these units stand up.
