I am looking for a leadpipe and receiver assembly for a Yamaha 621 (not 641). It's part number G3120520.

The 621 is a non-compensating 3+1 with large shank receiver. From what I've heard these leadpipes are the best solution to making the 321 work with large shank mouthpieces. Yamaha is backordered.

If you've got one let me know!

Thanks!

Kris
