Sorry, I know you're after a match but I have found only a similar for now: Design System. The main big difference is the /K, the rest is very close.

EDIT: talking about this /K, it's clearly not as "gas-pipe" as the rest of the lettering... As it is was for a signage, they've may be decided to change and go with another /K to avoid any misreading because, as most of gas-pipe style fonts, the /K could be very (too) close to /H and so confusing.
