Help to identify an Antoine Courtois trombone

[Nordsealand]

Im looking to buy a trombone and have found a used i think might be good fit. Problem is that the current owner isnt sure on the model, and its a bit far out (couple hours drive) for something im not sure what is. Its a small bore Antoine Courtois Paris model (says so on the bell), with yellow brass. It has the small black AC-logo on its counter weight, and the the two rods connecting the halves on the slide (unsure what their proper name is, but its where you holde the trombone) are not curved like some of AC’s other models. Does anyone know what model this could be or is the description to vague?
Best regards
