J frame magna grips with diamond

[kc-130nav]

You can see that I have been searching for some correct grips for my 1964 model 28-2

I just left an estate sale and found some what I believe are J frame magna grips. Please see pictures and help me confirm what I have.

They look like J frame size grips, but difficult to tell for sure w/o scale.

However, they are not factory grips.

Thanks. After posting I realized they don’t have the disc on inside

They are indeed j frame rd butt but not factory. They are modern reproductions.
