I believe i have the same axe as the one pictured, though sold under the "LUX" store-brand at a German "Home Depot" equivalent called "Obi". Mine has a blue color instead of the green in the Mueller photo... The shape, weight is exactly the same - as much as i can tell from the photo on that site.
Mine did come from the store needing to be sharpened (something i'm in the process of - as well as re-profiling a bit to a slighter angle).
EDIT:
OK, sorry, i needed to get over seeing my axe on the internet!!!
The axe itself is OK, but the alignment isn't as straight as i'd like. However, that may aid in splitting - i haven't actually gotten out with it yet.
In hand, it seems a little "head-heavy" for the length, but it's not too bad. I think i'd like a slightly shorter handle, but again it's pretty good. My axe's over all length is exactly 60cm meaning 23.62" - round up and you've got 24" and yep, it's from Ash.
I looked at the "Additional Images" and the handle on my axe is shaped/curved differently, but the head is a dead-ringer.
I'll try to take some pics and post 'em up... Maybe it's not the same maker, but if not it's an absolute, exact copy.
EDIT II:
My axe is a "Helko Werk" brand so probably different in some way..... Sorry....
