I'm looking for a replacement neck for a vintage Kohlert alto clarinet.
The type needed is one that is corked at one end and inserts into the top joint of the instrument itself (i.e., rather than into a metal coupling with a screw like a Bundy or a Vito). Like this one: http://www.music-oldtimer.com/en/ins...08-kohlert-co#
Anyone? Does anyone have suggestions on where to look for such items? Any guidance is much appreciated.

If you don't have any luck with finding a suitable replacement, measure the bore diameter and a new one can probably be made from nickel silver tubing of the same internal diameter with a tenon and socket machined and soldered on (and plated if need be). Some experimenting will have to be done to find the correct length, or maybe you could have a tuning slide fitted to the socket so it can be adjusted.

Chris, any ideas for sources of nickel-silver tubing? I haven't found any yet, and I sure could use some in various sizes.

You may have to get it specially made/drawn to the correct diameter. I don't know who sells it in the UK or the US - Howarth used to buy it for making socket linings from but now they're CNC machined from thick walled nickel silver tube.
You want it around 1mm thick for strength - probably best contacting the Howarth factory as they may be able to tell you who supplies it. Only thing is the price of nickel silver has shot up in recent years compared to what it was. Email them at: worthing@howarth.uk.com
I've searched but can't find anything near the diameter needed for an alto crook (I assume it'll be around 17mm as I think only Leblanc used 18mm) and making seamed tubing from sheet nickel silver could end up being more troublesome than it sounds.

Take a look at some of the copper fittings at the local hardware/plumbing store. I made a short neck for my Selmer basset horn from those parts which is handy when the temperature is cold or when it takes a long time for the instrument to come up to 440 pitch with the normal neck. The diameter may be not right, however.
The Selmer USA accessories catalog may have necks for their alto clarinets but they may be not the right size. Good luck!
