Hello all. I’ve had this cello since buying (new I think) from a music store in Cambridge (UK) in 1999. I’ve been thinking about selling it recently, but I have no idea what it is. There is no serial number (I even used a fibre optic scope to look inside). Only a sticker saying “Made in Germany”. Pretty sure it’s 4/4 (30” back, 48” total length). Likely a student cello.

I will add those photos soon)
