msa firehawk model 10061364 confined space escape pack

Description

These were purchased in 2011.  They were never used inside of a confined space.  They were purchased and then placed on a shelf for the most part.  Two of them still have some air in them.  They will need updated hydrotesting.  The regulator fits in the MSA Firehawk masks.
Please let me know if you have other questions. They do not come with masks.  These sell for about ,500 brand new in todays market with the mask.
