He had patents in other country ...

Also that picture looks like it is a photocopy of the original drawing .

I know he applied in canada and england .

Mark:

While that is true, it does not account that they did not have photo copy machines back then and for one drawing to have the exact coil as used in another drawing, only it is reversed, is next to impossible. (Nice find Jeanna)

I am doing some more research into this and will keep you all posted.  That is all I can say for now.

Good Bill,
I do see your magnification.
Did you see my improved version?
I changed the color and contrast etc to be almost exact.

Mark,
Perhaps this other country patent drawing would show the other pieces that are missing from what I could fine, but I do not know why a tracing would show up some of those lines.
It is not much, but unlikely to be real....which I find disappointing.

On the other hand...
There is a heavy 'shadow' line on the edges of the patent wooden core pieces that is not there on the new one on the bottom.

@jeanna

Here is the british one http://v3.espacenet.com/publicationDetails/originalDocument?CC=GB&NR=189807577A&KC=A&FT=D&date=18980520&DB=EPODOC&locale=en_V3

Also i had a look at the 2 photo you posted , they are not the same ?


@pirate

You are right back then they did not have photocopier but they had skills ...

What i tried to say is at one point it was a drawing , and had to be scanned , and is it the original . Because lets say i met NS kids , and they had old drawings , i would love to make a copy , the easiest way would cost 10 cents .

Also NS patent drawing are made by professional , that would account for precise drawing and use of see trough paper for exactitude .
