Thanks all or your info. I had a suspicion that it was a Otto Busch. But I couldn't find much info about the particular type blade in combination with these scales.

In the meantime I have received the blade. It shows no major damage, pitting or hone wear. So I think it is a good buy. Although the scales are nice in their own respect, I do not like them.

I was thinking about ordering the plastic TI blades from classic shaving, but since I a from Europe shipment costs add up. And I have no idea if the TI scales ooze quality. These scales do slightly, but I think they are a bit flimsy. I like sturdyness and a slightly more modern look.

I like the style of the TI scales and ofcoure love the metal hand machined color filled scales self made on this forum, but I think they are out of my budget.

Does someone have a nice alternative? Thanks!
