Trying to find the font for this company's dimensional letters on Building Sign and Monument Sign - Beus Gilbert McGroder

[Member cmi…]

Medium Roman Standard is the closest I can find, but it's not quite right.

It looks to me like an Engraving Serif – kind of the opposite of something used for cutout letters.
Not identical but in a similar vein as Sackers Roman with the R filled in a bit.
