Hello, this appears to be a mixed bag of hand-drawn or modified lettering with some metal Spacerite alphabets. You can see that the ‘R’ changes quite a bit at each size.
It is likely that the Spacerite Modified Roman alphabet was used for the endearment, the given name and the date lines, but was modified by hand to be bolder for use as raised lettering. The surname is the Spacerite Double Outline alphabet with the second outline ignored by the stencil cutter—which was common and in fact recommended in the original sales materials when the metal alphabet was first released in the early 1940s.
It will need to be custom matched. Feel free to use the Inscription Matching Service if you would like help.
