Hey all! First time poster here and just have a couple of quick questions I hope somebody can help me with! I pulled out my old Leblanc Dynamic H today, and the insturment seems to have large spotty patches where the black isn't as black, and some parts almost look white! It's been kept inside it's case for a year, so I'm a tad confused. Here is a pic - sorry it's not very clear, I'm having serious camera issues -_- I'm aware that sunlight can cause discolouration, but it has been kept inside of the case, in the shade of my wardrobe! I at first thought it might be surface mould or something, but after a (gentle) scrub, nothing seems to be coming off. The metalwork is all fine - it seems as though it is the wood/stain itself. Every piece of the clarinet is plagued with this, apart from the mouthpiece (which has been covered with a metal cap). Even the sides which were face down in the case are affected! So... a) Does anybody have any ideas as to what this could be? b) Is it purely cosmetic? Could there be repercussions down the line? (Wood too dry causing a crack or something)? As said - the clarinet itself is an old Leblanc Dynamic H. As for how old it is - I've been trying to find that out for a while so I wonder if anybody could help me? I got in touch with the shop I got it from - all they said is that an elderly gentleman sold it to them about a year before I picked it up (2008ish) and that he had owned it for a while. I can't seem to find any information online regarding serial numbers. I came across this, http://www.dannychesnut.com/Music/Clarinet/Leblanc/LeblancSerialNumbers.htm But I'm struggling to find anything that relates directly to the Dynamic H (and that website is playing up for me)! My S/N is 546** - any ideas? And if anybody could have a guesstimate of value, I'd be interested in knowing! Thank you very much for any help anybody can give it, it is hugely appreciated!
