Olds Special trombone

[karsseboom]

Hello all,

I am looking at buying a Old Special trombone for my dad as a gift. I am a trumpet player and have played on a olds Custom P22L trumpet for years and love it.

I am wonder how the Olds Special trombones are?
The Serial number 9814xx and I think it is Roughly made around 1976??

My dad currently plays on a Yamaha Z model, the one designed by Al Kay if this helps at all.

Thanks in advance
