It's nice to see that there are still some enthusiasts out there
@Atlantia:
The figure-of-eight guard was used well into the 20. century (AFAIK they were tournament legal in the US until 1956, even though nobody used them at that time any more).
I'm unable to post pictures of my weapon, sorry. But the markings are generally the same. Mine is missing the Siegel-Cooper marking. But this is self-explanatory, because my weapon was not imported into the US, therefore needed no retailer. The "L" is missing on my weapon, because the marking is not very clear.
@ katana
Nice to "see" you again
I don't think so, because:
a) the weapon is right handed
b) look at the picture
c) I've never heard about markings which indicate for what type weapon the blade should be used. Generally the french blade can be used in a pistol grip whitout much conversion. The italian blade only fits italian handles and the french blade could be used under special circumstances on an italian weapon as well. There would be no need to mark it this way.
But I must admit: Clever guess.
I've never thought about that.
