The P.C.40 was the last main civilian mask design produced in Italy before the end of the war.

Mask overview Edit

Left side markings

The P.C. 40 was very similar to the P.C. 35, but it was cheaper to produce: the rubber was thinner and the eyepieces were made of acetyl cellulose, much less sturdy than Triplex glass used in previous masks. The exhale valve is in the front and it's covered by a removable lid for protection. The filter intake is at the bottom. The inhale valve is a rubber disc just above the filter intake. The mask uses a simplified Italian five straps system.

Filter Edit

The filter had the same shape as the Pirec38 filter but was painted yellow. It featured a paper disc on the intake that was to be removed when the mask was to be used.

Kit Edit

The mask came in two different kits: most masks were stored in a cardboard box and came with the filter, a stick of anti-fogging soap and the manual. Some masks had a dedicated cheaper variation of the T.35 bag and had the same accessories.

Variants Edit

Post-war Edit

After the end of the war, the production of this mask did not cease but switched to different materials and hardware, while maintaining the same setup.

Wearing the P.C. 40

The main differences are:

  • The rubber used was blue-grey colored, it was more durable than the older mixes
  • The intake piece was the one later used for the M59, with minor structural differences to the original one
  • The eyepieces were made of Triplex glass instead of acetyl cellulose
  • The harness was the same one as the T.35 instead of the cheaper alternative regular P.C. 40s sport
The use, kit and distribution of this mask are unknown, as no info has been found on the topic.
