Le Thiernois razor information

Hi guys,

Today I won an auction on ebay for this beautifull french razor. The only problem is that I can' t find any info about the maker. All I find on Google is about a TI model with the same name and blade etching. Is the razor I won an older TI?

I think the 'DF' on the tang stands for Delafoulhouze, an excellent razor maker from the town of Thiers ('Thiernois' means 'from Thiers').
