FWIW,
I just completed the renovation of an old, wooden-combed Hohner 280 - cleaning/sterilizing, replacing the spikes with screws, sealing/repairing the comb, new valves etc., etc., - and my conclusion is (apart from the
experience or satisfaction of the actual renovation) I will stick with the plastic combs ('til I can afford one with an aluminum comb
)
I don't hear enough of a difference in the sound to make it worth the expense and time required to bring one of these old buggers up to scratch and the difference in the mouthpiece (IMO) makes them more uncomfortable.
...stick with plastic...
