Part information – please

Hi All,

I have a Hymatic P.E.C (part # MSC 201 or 2010) the lox tube has a date of 3/q/76.

I’m trying to find out any info regarding this item, seats the type was fitted to, aircraft etc.

So far the seach online has been limited to the company; Hymatic of Redditch but little else regarding the item in question.

Any and all help would be grateful.

Regards
Nigel
