This is the experimental Chinese TF-12D. Manufactured by TangFeng, it has a similar profile to the Avon M53 series, but is ultimately entirely different.

This is Cover’s Automatic Respirator. First patented in 1901, it was sold into the early 1970s! Sponge respirators were wholly obsolete by that time, but the masks continued to be sold because of the company’s stagnation prior to Bill Moon purchasing it.

My most recent acquisition, an MSA GB riot control mask! I’m gonna restore it, but I’ve gotta find a donor mask for the hose

Pictured is the complete American M17 series. From left to right: ABC-M17, M17A1, transitional period M17A2, and M17A2.
The M17A2 has the winterizing kit and the laser protective outserts mounted.

This is the M45, the previous-generation of gas mask for USSOCOM. It was replaced by the Avon M53. The C420 pouch and filters are modern.

This is the Dupor No. 20 from H. S. Cover Co.! It uses a pair of sponge filters intended to be soaked in water. The water would cool the air passing through the filters, earning the No. 20 the title of “water-cooled respirator”. It was mainly advertised to firemen.

This is the German VM40, a civil defense gas mask adopted in 1940. It differs from its predecessor (VM37) by replacing its helmet style design with a head harness to save rubber. The big flap on the front is its exhale valve.

Nothing historically interesting, I just thought this photo I took goes hard

Pictured is the Blue Box, an Automatic Respirator of an unknown make and model. It has been nicknamed that due to its distinct blue box without any markings or branding. The other box is for a late Cover’s Automatic Respirator and serves as a comparison.

This is the American M2-10A1-6 Lightweight Optical Mask. Its small, flat, and circular lenses are intended to interface more easily with artillery scopes, binoculars, or other optical devices. The threaded bar between them is used to adjust the interpupillary distance.

This is the Comfo Respirator with Hood from Mine Safety Appliances (MSA). It was a variation of the Comfo meant for use against especially abrasive dusts or to make bodily decontamination easier.

Pictured is an XM50 JSGPM from 2004. It’s an experimental version of what would become the M50 JSGPM. There are many differences between it and the finalized mask. Most notably, it uses a clear silicone oronasal cup and sealing disks.

This is the Bureau of Mines Box Respirator, the US military’s first attempt at a gas mask. Made in 1917, it failed due to its thin rubber that couldn’t withstand more abrasive chemical weapons like chloropicrin. The filtering elements of the Type A canister were segregated, too, lowering efficiency.

This is the Dupor No. 10 Chemical Cartridge Respirator from H. S. Cover Co.! It was a half-face respirator meant to protect the wearer from light concentrations of deleterious gases, vapors, and dusts. Here it is outfitted with a pair of organic vapor cartridges.

Here’s an infographic I drew a little while ago that demonstrates the differences between various automatic respirators. This is far from all of the ones known to exist. An AR is any mask based on H.R. Hurd’s original AR, or is based on one that is.

Here’s a Pro-Tech Model 1490 half-face respirator from the Pro-Fit series. The series also included the Model 1390 (made from monoprene) and the 1590 (made from silicone). The 1490 is made from PVC which allows it to conform to the face better by becoming more pliable when exposed to body heat.

Pictured is an American military ABC-M17. This mask featured internal ‘porkchop’ style filters which greatly reduced overall bulk. The M17 series would wind up being very successful, inspiring clones made across the world and serving into the 1990s.

Pictured is an American M9A1 gas mask with an M1 winterizing kit and an M11 canister. The dark green tinted lens outserts were designed to guard against snow blindness. The hood has a pocket for the exhale valve that retains heat so the condensation doesn’t freeze the valve shut!

This is my first post on Bluesky! Pictured is an All-Vision rebreather facepiece from MSA equipped with a Maskfone. This was a commercial mask and the Maskfone allowed the user to communicate with people outside a contaminated environment via a wired telephone system.
