4 valve front action version of the 20J

It looks to be in good shape. I can't tell for sure, but the last pic makes it look like either there's some scarring on the front bell that doesn't show up in the other pix, or it might have an additional (upright ?) bell. Fair deal either way.

Yeah. If I was 10 years younger I would jump on this. The 20j is hard enough for me to manage. I am just not sure where I would use this where my sousaphones wouldn't be appropriate and easier to carry.
