Imperial Touchdown I, Nib Question

[JPM-10]

Recently I acquired a Sheaffer Imperial Touchdown 1 in burgundy red.

A nice fountain pen made around 1960, in good working order. After some cleaning I could use it without any problems.

 

Normally I take some pictures of my fountain pens so with this one I did the same. The imprint of the nib is the reason for my posting het at FPN

 

Apart from the name Sheaffers, there is a R in a circle. ( see the photo’s) Is this simply meaning registered trade mark, or does it specify something else about the nib?

 

I think it is a EF nib, To compare it, I wrote the same text with three pens.

A sheaffer Imperial, a Pelikan Souverain F-nib, a parker slimfold F-nib.

As you look at the photo you can see the sheaffer has a finer line then the other two.

 

Is this R in the circle identifying a EF nib??

 

Who can tell me more?

Just the Registered symbol.

Oke thanks,

 

Is there a way to find out if the nib is EF, F or an acountacy nib?

Who can tell?

Only experience IIRC. Originally there was a chalk mark on the bottom of the section near the feed I think.

Oke thanks, Think it is EF by the feel of the pen and the line-width I get when writing.
