Width of RK30-91100 jack

[middlecalf]

If someone has an early (pre-‘63) RK30-91100 Jack if you could measure the base width at the widest point as shown in pic that’d be great. I want to compare to the variant A width. Thanks.

This RK30 91100 jack measures 4.5 inches across the base as indicated.

RK30 and early -35011 have the same footprint?
