I collected and sold the older wood body planes as well. These decorative wood mouldings were made with a series of more simpler blades. There is no need for us to be going round and round on this subject. Just post the link, please, that shows these highly unusual blade shapes (labeled knives2) so we can all learn. I could be wrong but it appears you posted some pictures of the finished product decorative wood mouldings and mistakenly labeled it as Knifes2.
Fancy wood moulding cutters from Carpenters Plows are very similar but are about 1/2 to 1/3 the width of what you posted. Look in my links above. It takes several blades to cut a moulding like those pictured. Good guess but IMO not a plane cutter.
www.southern-tool.com/store/13moldercutters.html as i said these are profiles of modern ones and yes
moldings were made with multiple planes and some made with a single blade.The planes for large crown moldings would be the 2 person type and single bladed. The one in this post looks like a chair rail molding profile? I believe a (this old house) episode shows the operation of the 2 person type.
