This is a BEAUTIFUL looking and fantastic playing Bach Strad. Large Bore (4.62) and plays like a dream. The valves and slides are great! Great laquer, with just a couple of minor issues, but none that can be seen more that a few feet away. No dings or dents. GREAT slotting above the staff. Great for lead, section work, orchestral, big band, or jazz! Serial number 422xxx, which puts it in the 1990's. 
The case is in excellent condition as well. This is a prize in every way!
