Correct Red for a Horni Fire Alarm Box


I inherited a Horni call box. Please excuse incorrect terminology I use. I'm new to this. Anyway, it's a pole mounted box used in Albany NY. My grandfather bought it from the city when they removed them from service, and my father stripped and sprayed gray primer on the outside prior to me getting the box from his estate in 2015. The inside of the box is the original red. My plan is to convert it into a table lamp. I've carefully removed the "guts" and am keeping them safe for someone to re-install, should they wish, after I'm gone. I'm being careful do nothing that's not reversible.

So, is there a spray can color that's close to the original Horni red that someone can recommend?
