Another inherited/found razor

[Ryu]

So I was talking with my dad and he remembered a box of misc stuff from my grandfather that had passed away a couple years ago that he hadn't got around to going through. We went through it and I found another blade to add to my collection/work list.
This is what I found:


Not horrible but not great. But edge on the blade looks alright.

The Etching on the blade reads (I think): (EDIT: saw in better light)
Acciaio diamante
Questo rasoio fa leggermente
Qualunque Barba dura e cattiva
It appears the blade has been worked over before as the etching is almost completely gone and you can see the marks from the poor "polishing/restoration" job.

The tang has a Pyramid with a cross and reads:
Gottlieb Hammesfahr
Solingen, Foche

The scales however are not in good shape. Horribly warped probably from sitting slightly open in the garage with items on then for 2 years.

Does anyone know anything about these razors?

From a blog post from mahan it appears this razor could have been produced between the late 1800s to mid 1950s. This is a much larger (almost 7/8) that the ones I received from my other grandfather (4/8 to 5/8) and longer as well. This one seems like a good candidate for some new scales and a mild restore on the blade. I'm afraid the etching is probably going to be a lost cause trying to save as I can barely read it now.

Hopefully Martin103 will be along to baffle me once more and his research/knowledge on the ways of straight razors.
