Apologies for my failure to communicate more clearly. I certainly didn't intend to take up so much of your time with this!
What I attempting to point out was simply that I find it very difficult to ascertain the relative spacing when the photos do not show the units at the same scale.
I'd have to either see them "in person", next to one-another, or a see a photo in which they were placed next to one-another, to ascertain whether the spacing is the same.
