Hi,

Recently I purchased a NOS Sheaffer Legacy (the first model, with squared ends), and when I unscrewed the section from the barrel, a black o-ring also came loose. I can roll it over the section's threads and screw the unit back together, but it always comes loose when unscrewing. In my Legacy II, there's an o-ring in a recessed part of the section, but the section appears differently designed than the Legacy I.

Where is this o-ring supposed to be located on a Legacy I, and how can I secure it to that location?

Thanks,

-Mike
