I wish to purchase a used Edwards 8 inch, yellow brass, un-soldered rim, tenor trombone bell—preferably 21 or 22 gauge. Christian Griego recommended a 129CF or 177CF. But I am open to other options as long as it is yellow brass, 8 inch diameter, with un-soldered rim. My budget is in the $330-500 range. If you have or no of one for sale, please contact me via email of private message. Email will elicit a faster response. Thanks!
