Custom Seydel 1847 Low Classic Harmonica

I bought a set of Seydel 1847 Classic harmonicas a few years ago and haven't played them, so I'm customising and selling them all.
I have the following keys: Low Low F, Low G, Low A, Low Bb, Low C, Low Db, Low D, Low Eb, Low E, Low F, G (2), A, Bb (2), C (2), and D.

Low Low F, Low G, Low A, Low Bb, Low C, Low D, Low Eb, Low E, and Low F have SOLD. The only remaining low harp is Low Db.

These are the Low harps.
These harps come with the following customisation: flat sanding of the bottom reed plate (enhancing air-tightness and ease of breath control), retuning to just intonation (perfect if you like that old classic harmonica tuning the great players used), and reed adjustment (improving sound fullness, loudness, purity, and clarity of tone). This creates a harp much better than stock that has great chords, pure notes, and a strong sense of precision and control.
Lastly, the Low Db is an older model. Instead of having the oversized cover plates, it has a dent in the lower cover plate for hole 1 inhale to aid reed clearance, and the comb is the same thickness as 1847 Classics in the keys of G to F#.
If you have any questions, please ask me anything.
