recently I bought exactly the same easel!
It's beautifully made, most likely the best one I have used in 30+ years of photography.
Mine is marked "Leitz -Wetzlar" in red circle, same as for Leica cameras.
I paid it around Can$50
If you live in US or UK (imperial system) then you will need to buy another one 11x14" or 16x20" (if you plan to print bigger prints?) since this one is good for 8x10" and little bit bigger prints.
All the best!
