Font Identity, block font with bevel

Not even sure how to describe the font to help my search. This is individual alphabet set, client would like to match to add more letters to their collection. But I haven’t been able to match the font with the 3D bevel…unless it was done separately.


I believe that is a Gemini Pronto Changeable Letter. It is a pre-made product by Gemini Sign Products. They refer to the font as “AD.”
They do not sell direct (though some companies sell online using a variant of their name).
They should be available to order through most sign companies.
