Gasser head ID please?

Can anyone identify this gasser head please? And will it run from an I90 PSU?

Looks like a Coherent "Enterprise" that's been skinned..

I-70 MARIA Medical Tube, and the I-90 supply will probably do a "low tube voltage error" and maybe shutdown. It looks like the wrong/no ignitor is installed for a I-90 supply. Clue = Way too long to be a Enterprise. Oversized gas ballast + fill system makes it medical. Oversized ballast to reduce the requirement for tube replacement/field service.
