Hi all! I'm considering buying some secondhand Lachenals online but the descriptions have a ton of abbreviations I'm not familiar with... could someone help "translate"?
Opt 1: Lachenal Anglo Concertina, 20k, BB, RE, SR, 6F, CP
Opt 2: Lachenal 20 key Anglo Concertina 5F WE BB concert pitch refurbished exc. cond.
I think "BB" means they have bones buttons and that "WE"/"RE" means wood ends and raised ends, respectively, but I am struggling past that. Thank you!
