Comments on Salamander Razors

I am beginning to cull my herd and am looking for advice/comments on three small razors by Salamander Works.

They are marked;

Salamander - Works
Made in Germany
Foche - Solingen

Any ideas of their worth, collectible status and/or shaveability? They are all small blades 5/8 or smaller.

Thank you,
John

John,
I have one of the Salamanders (was my Grandfather's) with the same markings as yours. After I lapped my Norton, it honed well and now shaves nicely. I like the narrow blade as it trims my mustache nicley. No idea as to collectibility.
