Fire bottles

Not sure if any help, but attached are some pics of a Graviner TYPE182A bottle.

Although marked with Sec 27N there is no Ref Number stamped on the unit. I believe this bottle is for Dove/ern application.

My knowledge of Graviner products is limited, but with some of these type of units the bottles are the same it’s the fittings that ar different for each application.

Flytst have also sent you a PM
