I have a Conn H4 bell with a Yamaha 200ad slide and a Yamaha 200ad threaded receiver on the bell section.
I have a chance to buy a Yamaha 352 in silver with ruined slides and wondering my 200ad slides will fit?

Thanks for any comments

Only one way to find out, unless someone can dig up the part numbers for the YSL-352

I was hoping to hear from a brass repair technician but appreciate your response. Cheers
