These are .525" horns. They look like they may be based on the Bach 36B.

I've owned a few AC420s, based on the Bach 42, and they were really excellent horns. I'd like to know what the 260s are like.

Basically it is a copy of the Courtois 420 series. There is a .547 horn too (AC280). They both share the same bell but the slides are different bores. They also have a movable thumb trigger and forged water key assembly taken from the pro series. The case is quite nice too.

I have a 280, slide is best I have ever had. Fantastic horns for the price.
