@OldSchoolEuph A quick vote of thanks to OldSchoolEuph for posting this info and to all those members who have offer informed thoughts and commentary.
It's this type of posting that drew me TH and the late lamented TM in the first instance. I would not deny that there is room for this type of information and social intercourse, however I would suggest that the more learned material that is posted, the greater the possibility for the site to attract a wider membership base.
Notice the mix of makers as far as component parts on some of these examples.
When it comes to Muck, I wouldn't rule anything out. Like Rolls-Royce, what started out crafted in-house with some sub-assemblies supplied transitioned over time into a brand/company that was nothing but production coordination - no fabrication.
I just joined so am still trying to figure out the "rhythm" of this site.
I have one - it has "ATR213 Czech Republic" on the receiver, a stylized "ak" logo on the bell and s/n 227190 vertical on the bottom of the 2nd valve casing.
It appears to have had little use. The lacquer is perfect and no dents, dings or scratches. The valves seal well and have quick response. It appears well-built and is actually a good player. Would this be considered a student model or something above that?
