This is a genuine bell for a Marigaux M2 oboe. I purchased it last year as a replacement bell for my usual 900 series oboe, but I ended up preferring the weight balance and sound of the original bell, so I only tried this one about 5 times after purchasing it. Therefore, it's in almost new condition. It will fit not only recent Marigaux oboes, but also those with older serial numbers. (I used it with a serial number in the 18000s.) I also believe it can be used with Yamaha instruments. The key joints are silver-plated, the pads are leather for B♭, and the resonance keys are cork. There are no chips or damage on the edge of the bell's bottom. The current retail price is approximately 173,000 yen. I am considering a slight price reduction. Thank you for your interest.
