A couple of weeks ago I bought a L'Essor razor for $20 and along with that razor came a straight razor "Thiers Issard".
Now, I know a fair bit about DE and SE razors but straights are very much an unexplored area for me.

In essence I'm curious to learn any history/dating of this razor.
I've tried Googling for it but it's hard to search for the number 17 along with the brand name and come up with a good thread/info.

Also, is this razor 'good enough' to have honed up and put to use - or is it better suited as a shelf-display?

Thanks in advance!

Here's a bunch of photos....

The case says "69" but the razor itself says "17" so I'm guessing it's not the original case.

Does the "17" on the razor help in dating it more accurately?

To my untrained eye it looks like it's in good shape (there are no cracks or any chips in the scales and no, as far as I can see issues with the blade) - but I would love to hear from people more SR-savvy than I am.

Hone and use - or shelf-piece?

Front of the razor shows, I believe, that it's a "true" frameback?


The end of the scales have a white 'insert';
