Corrugated Planes

To date (4/15) we have information that suggests that Corrugated planes were produced across the whole range of WS bench planes, since we have examples of A4(C), A5(C)and A7(C).    It must be presumed therefore that the intermediate planes would have also been produced with a corrugated sole.  However it should be noted that the planes were never cast with a ‘C‘ designation on the body.

To date I have in my collection A4(C); A5(C) and A7(C) and I am looking for information on the other sizes, in order to post here.

A4(C):

This plane has 10 corrugated lines and each was 1/16″ in width:

     

Heel                                                                                                                                      Toe

A5(C):

The A5 corrugated version was obviously very similar to the A4(C), having 10 lines of corrugation and each being 1/16″ in width. Note below the differences in the front and end start points of the corrugations etc.

                      

Heel                                                                                                              Toe

A6(C):

This plane has 12 corrugated lines, again only 1/16″ in width, see below for some front and end start points etc.

A7(C):

This plane has 12 corrugated lines, again only 1/16″ in width, see below for some front and end start points etc.

I recently purchased an A4(C) in the box, and I am certain that the box came originally with that plane.   BUT the box label is a standard A4 label with no indication that the plane within the box is corrugated, which makes me wonder as to how the wholesalers or retailers of that time could tell whether the plane in the box was corrugated or not, without opening each box!

I will post other Corrugated plane base photos as they may come available to me.
