Odd ‘o T swiss T o’

[sem.gilst]

Hi,

On my 1803 on the bottom there is written ‘o T swiss T o’. I can’t find what it means, other than swiss T or swiss made. I think it had something to do with the percentage tritium that there is inside.

Someone out here who can share his knowledge?

Thanks in advance.

Please search for ‘1803 linen sigma’ to get some pictures where you can see it. (new here so i can’t post pictures).
