Conway Stewart 475

[Aus_FP_Enthusiast]

Hi all

 

A family member gave me this pen the other day; a 1935-1940 Conway Stewart 475.

When I got it there was no ink sac installed and as a result I need to put a new one in. Does anyone know the correct size sac I should use?

 

It came apart very easily and it has now been completely cleaned. The plating has completely been worn off on the lever.

Also, does anyone happen to know if the lettering on the body of the pen was originally filled in with white/gold paint to make the name stand out more?

Thanks very much
BP

I think a #16 sac is what you need. I have a few CS pens, and they have all taken the #16.

Thanks! Today I cleaned all the old shellac off the sac peg? and measured the diameter with my micrometer. I got exactly 7mm, so would I go with the sac #16 which is for a pen with a barrel diameter of at least 6.5mm or a sac #17 with a barrel diameter of at least 7.0mm?

 

Cheers

7 mm = .27 inches. I checked that with a section that I know takes a #16, and it fits right. Try the #16 sac.

A bit obvious I know, and you probably have already, but check the original sac hasn't just hardened and stuck inside the barrel in which case you would need to carefully pick it out. Been there, seen that.....

regarding the other question as to whether white/gold paint was used to highlight the barrel imprint - the answer is no. Some collectors use a white coloured abrasive/polishing compound when renovating f.ps., and this will leave some residue within the imprint which appears to be permanent, and on a black pen this has some attraction, and can make barrel imprints that are less than legible more easy to see and read.

These are commercially available compounds/papers under the names of Micro-Mesh and water based Micro-Gloss in grits ranging from about 1500 to 12000 in both sheet form like wet and dry papers, and liquid form, and unlike some of the silicon based polishing products don't leave a residue coating on the plastic. They really do work.

 

This is not to be confused with 'chalk marks' which are factory applied marks, mostly in white and on the barrel, indicating model/nib details - although have to say I've no idea how permanent chalk marks are.

Not very, they can be rubbed off with a polishing cloth.
