Apt Holman préamplifier : What font used for the wording ?

Hello,
I own a fine piece of kit, but alas, the wordings on the front face are disappearing from use.
I've found someone able to laser print the new wording on the front panel after powder coating.
But, they ask me what font and at what size to use ....
Does anybody know what font was used ? Or have a clue ?
Many thanks in advance for your help !
Have a bright and nice day !
