Fascinating to see it was made by "Pyrene Manufacturing Company".
Here in the UK the name 'Pyrene' would be familiar to people in the 40s/50s/60s for brass-cased 'syringe' fire-extinguishers, many of which contained Carbon Tetrachloride! Squirt that on to any hot metal and you created Phosgene gas! Which was probably more-likely to kill you than the fire you were trying to extinguish.
